1/4 Vehicle Vibration Reduction Performance Evaluation System

Classification:

The 1/4 vibration table is mainly used to verify the vibration performance test of vehicle suspension mounted dampers, the company can design special dampers according to all kinds of passenger cars on the market, or design a general-purpose 1/4 vibration table, with different suspension dampers for testing. The 1/4 vibration table can provide sine wave, triangle wave, square wave, sine sweep frequency and random road spectrum excitation, and can also reserve the interface to import different road spectrum information collected by the vehicle. The experimental system also has the characteristics of data acquisition, real-time control, online parameter adjustment and damper vibration reduction performance index evaluation.
