3-Ton Chassis Dynamometer

Working principle of 3-Ton Chassis Dynamometer

The driving wheels of the vehicle drive the main and auxiliary rollers to rotate. In the absence of slippage on the tire and roller surfaces, the linear speed on the roller surface is the driving speed of the vehicle. The speed sensor installed on the active roller outputs a pulse signal, and the pulse frequency is proportional to the roller speed.

The road resistance during driving is simulated by eddy current loading, and the translational inertia of the vehicle and the rotational inertia of non-driving wheels are simulated by the flywheel inertia system.

When the excitation current of the eddy current machine interacts with the rotating external magnetic field, a braking torque is generated, which reacts on the surface of the roller and acts on the S-shaped pressure sensor through the force arm. The output analog signal of the sensor is proportional to the magnitude of the braking torque.

According to relevant physical theorems, the power P can be calculated with the vehicle speed (speed) and traction force (torque).
