Car Suspension Tester

Working principle of Car Suspension Tester:

The vehicle is parked at the designated position and is forced to vibrate on the tester and the suspension device of the vehicle through an exciter composed of an electric motor, eccentric wheel, energy storage flywheel, and spring. After turning on the tester for a few seconds, disconnect the power supply to the motor, thereby generating sweep frequency excitation from the energy storage flywheel. Due to the higher frequency of the motor compared to the natural frequency of the wheel, the sweeping excitation process of the energy storage flywheel gradually decelerating can always sweep to the natural vibration frequency of the wheel, causing resonance in the test plate and the vehicle. By detecting the vibration curve of force or displacement during the vibration attenuation process after excitation, the frequency and attenuation characteristics can be determined to determine the performance of the suspension damper.

Characteristics:

1) It is welded from a solid square steel pipe and carbon steel plate structure, with a sturdy structure, high strength and beautiful appearance.

2) The measurement components use high-precision force and wheel load sensors, with precise and accurate data.

3) The signal connection interface adopts an aviation plug design, which ensures fast and efficient installation, stable and reliable data.

4) It has strong compatibility and can be compatible with different vehicle models for testing.
