In addition to being used to determine the torque or power characteristics of a machine under test, dynamometers are employed in a number of other roles. In standard emissions testing cycles such as those defined by the United States Environmental Protection Agencydynamometers are used to provide simulated road loading of either the engine using an engine dynamometer or full powertrain using a chassis dynamometer.

Beyond simple power and torque measurements, dynamometers can be used as part of a testbed for a variety of engine development activities, such as the calibration of engine management controllers, detailed investigations into combustion behavior, and tribology. In the medical terminology, hand-held dynamometers are used for routine screening of grip and hand strengthand the initial and ongoing evaluation of patients with hand trauma or dysfunction.

They are also used to measure grip strength in patients where compromise of the cervical nerve roots or peripheral nerves is suspected.

Typically the force applied to a lever or through a cable is measured and then converted to a moment of force by multiplying by the perpendicular distance from the force to the axis of the level.

An absorbing dynamometer acts as a load that is driven by the prime mover that is under test e. Pelton wheel. The dynamometer must be able to operate at any speed and load to any level of torque that the test requires.

Absorbing dynamometers are not to be confused with "inertia" dynamometers, which calculate power solely by measuring power required to accelerate a known mass drive roller and provide no variable load to the prime mover. An absorption dynamometer is usually equipped with some means of measuring the operating torque and speed. The power absorption unit PAU of a dynamometer absorbs the power developed by the prime mover. This power absorbed by the dynamometer is then converted into heat, which generally dissipates into the ambient air or transfers to cooling water that dissipates into the air.

Absorption dynamometers can be equipped with two types of control systems to provide different main test types. The dynamometer has a "braking" torque regulator - the power absorption unit is configured to provide a set braking force torque load, while the prime mover is configured to operate at whatever throttle opening, fuel delivery rate, or any other variable it is desired to test.

The prime mover is then allowed to accelerate the engine through the desired speed or RPM range. Constant force test routines require the PAU to be set slightly torque deficient as referenced to prime mover output to allow some rate of acceleration. Power is calculated based on rotational speed x torque x constant. The constant varies depending on the units used. If the dynamometer has a speed regulator human or computerthe PAU provides a variable amount of braking force torque that is necessary to cause the prime mover to operate at the desired single test speed or RPM.

The PAU braking load applied to the prime mover can be manually controlled or determined by a computer. Most systems employ eddy current, oil hydraulic, or DC motor produced loads because of their linear and quick load change abilities. Power is calculated based on rotational speed x torque x constant, with the constant varying with the output unit desired and the input units used.

A motoring dynamometer acts as a motor that drives the equipment under test. It must be able to drive the equipment at any speed and develop any level of torque that the test requires.

In common usage, AC or DC motors are used to drive the equipment or "load" device. An absorption unit consists of some type of rotor in a housing. The rotor is coupled to the engine or other equipment under test and is free to rotate at whatever speed is required for the test. Some means is provided to develop a braking torque between the rotor and housing of the dynamometer.

One means for measuring torque is to mount the dynamometer housing so that it is free to turn except as restrained by a torque arm. The housing can be made free to rotate by using trunnions connected to each end of the housing to support it in pedestal-mounted trunnion bearings. The torque arm is connected to the dyno housing and a weighing scale is positioned so that it measures the force exerted by the dyno housing in attempting to rotate.Test Cell Safety should always be your top priority.

Your test cell operators are your biggest assets and their health and safety is of the highest importance. Your ability to keep them safe also has a direct impact on productivity. One way to address test cell safety is by taking operators out of the test cell altogether, thanks to advanced instrumentation and control systems. Ergonomically, this maximizes productivity by reducing operator fatigue and discomfort.

You should also invest in test cell equipment that keeps your test cell safe. Below are just a few examples, contact us to learn more. Smart features, enabled by data acquisition and control systems, provide monitoring features and automatic fault actions to safeguard against potential damage to your system. With smart features, you mitigate potential harm to your dynamometer and test cell, not to mention possible damage to the engine being tested and downtime which impacts service to customers.

A Driveshaft Guard is installed between the dyno and engine and is designed to absorb the energy from the driveshaft in the event of a failure. The Driveshaft Guard acts as a shield surrounding the driveshaft and prevents excessive damage. If your Driveshaft Guard is equipped with interceptor tubes, this provides an additional level of safety by helping to absorb the energy, reduce the motion of the failed driveshaft and safely bring the rotating equipment to a stop.

All test cells should have an emergency shutdown procedure in place. Emergency stop kits are designed to power down the system in the event of an emergency. Traditionally, emergency stop kits shut off electrical power from all devices associated with the running of the engine. Install these kits in the proper locations so that the stop button is easily accessible and can be pushed immediately in case of an emergency.

Safety alarms should also be installed. Your test cell should have a separate fire suppression and alarm system. Since a potential test cell fire will be oil, diesel fuel or natural gas in origin, a water sprinkling system will not be effective. Instead, a fire suppression system for petroleum product-fed fires is recommended. Ensure your system meets the requirements of your local fire protection regulations.

A simple text-only link e. So, like many of our customers, we needed a new dynamometer test cell several in our case. This project offered an opportunity to detail the steps involved in constructing state-of-the-art sound-dampened dyno control rooms, engine cells, and chassis bays. First, review your requirements. Likewise, a trailerable chassis dyno used only to visit motorcycle events can live without a testing bay. In most cases though, a quiet and well ventilated indoor test room is almost a necessity.

Internal combustion engines generate plenty of noise, fumes, and heat.

What Is A Chassis Dyno?

An increase in STC of 3 is noticeable. An increase in STC of 10 cuts noise in half. Watch hear a block-cell's sound demonstration video!

Watch hear a modular-cell's sound demonstration video! A sound-dampening membrane or mastic i. A downside to concrete is noise reverberating off its hard flat surfaces.

Inside, the cell becomes an echo chamber, and may be unpleasant for technicians to work in. These blocks are cast with two narrow slits in one face, which lead into internal dampening cavities. These cavities are also fitted with fiber-faced metal sound baffles see figure below.

Painting concrete blocks both sides materially improves their sound-blocking properties. No matter what materials are used, walls and ceilings should be finished in a light color to aid visibility. Concrete and steel construction offers the additional benefit of inflammability.

However, although these proven solutions boast impressive STC numbers, much of their rating is earned at higher frequencies. The thundering noise of a big bike engine on a dyno is comparatively low in frequency — where nothing blocks the sound like high-mass walls and ceilings e.

The size of a cell impacts its total sound transmission, ventilation requirements, and construction costs. Keeping room, and window, sizes down reduces all three. Just make certain you allow enough elbow room to comfortably work on your engines and equipment. Typical minimum sizes might be:.

Ventilation is one of the more expensive components of cell construction — but avoid any urge to skimp on it. This necessitates a high-Hp blower and large duct work — especially for a large truck or race car chassis dyno bay.

Some videos and comments have surfaced of owners irresponsibly using this mode on public roads which endangers public safety. Do not do this. There are various types, but all of them generally work by providing a way for the car to send power to the drive wheels without actually moving the vehicle, and then the dyno records the power output of the car.

Dynamometer (Dyno) Driveshafts and Driveshaft Guards

Dynos are used by car companies and enthusiasts to test power output, by aftermarket customizers to test the effectiveness of their modifications, and by regulatory agencies to measure efficiency. Now, word has gotten out about how to activate this mode, and Electrek is here to remind you not to use it on public roads. It is dangerous, you have a high likelihood of crashing your car and endangering yourself and others. At the very least causing significant damage to your vehicle which will likely take a long time to repair.

Traction control works by automatically cutting power to the drive wheels in the event of loss of traction, allowing the wheels to regain traction which then helps to stop your car from spinning out of control.

dyno safety

This system will also cut regenerative braking if wheel slip is detected. This is actually a safety feature because traction control works by reducing torque to slipping wheels. This is somewhat analogous to how anti-lock brakes work but anti-lock brakes are not disabled by dyno mode. Automatic emergency braking automatically applies the brakes if the car detects an impending collision, a slow-moving or stationary object in front of the car which the car is certain to crash into. It is meant to reduce the severity of accidents and occasionally avoid them completely, but should not be relied on for this.

Stability control selectively applies brakes to individual wheels based on which wheel is slipping. If the car detects that you are understeering or oversteering, it can apply brakes specifically to the correct wheels in order to bring the car back under control. Every new car on the road these days is required to have stability control.

Experienced professional drivers have techniques to help mitigate the loss of traction and bring a car back into control, but these take a lot of practice before they become instinct.

These techniques actually often involve overcoming your natural instincts. It takes practice on a closed course or in a realistic driving simulator to train yourself to use techniques like these properly. In limited circumstances, for a highly-experienced driver on a closed course or racetrack, there can be performance benefits to turning off traction and stability control. Turning off traction control and stability control offer no benefit in normal driving circumstances.

All it does is make your car less predictable and less safe. It has been tuned by professional racing drivers to give you optimal control over the vehicle in a track situation. Other methods have been found to defeat Tesla safety systems before, but these were more complicated than enabling dyno mode.

Dyno mode was a secret in software until the information got out recently. We do this because we want to reiterate that you should not use dyno mode. Those safety systems exist for good reason and you do not gain benefits from turning them off. What we will do is show you a video of exactly why this is a bad idea.

One owner recently posted a video of himself activating it in a relatively normal scenario, a lightly curving freeway onramp. He has a dual motor non-performance Tesla, which is less powerful and less susceptible to oversteer respectively than a performance or a rear-wheel-drive Tesla.

All for a relatively innocuous stunt accelerating onto a freeway. Other comments have cropped up of drivers who have managed to damage their cars, breaking wheels or suspension arms on curbs, and so on.

Some videos have been made by Tesla YouTubers on closed courses.
