Our chassis dynamometers for climatic testing are available as standard in single roller, 2WD, 4WD and independent configurations.
The precision manufactured rollers are available from 0.5 m to 2.5 m in diameter, running in rolling element bearings which may be temperature controlled according to the application. Roller assemblies can be coated to increase tyre traction.
Trunnion mounted AC motors which compensate for system losses and simulate road load forces, vehicle inertia, and gradient are mounted on the dynamometer base frame. Insulated floor plates and roller covers protect the motors from extremes of temperature.
The dynamometer base frame can be mounted on a moving carriage to provide wheelbase adjustment to accommodate different vehicles. Roller centres can be set automatically as part of the road load model information, or set to the user’s specific dimensions.
The test bench is equipped with the PAtools real-time system and a distributed I/O architecture.
