Description

technical field [0001] The invention relates to a shock absorber test bench for the performance test of the shock absorber of motor vehicles such as automobiles and railway vehicles. Background technique [0002] The shock absorber test bench is one of the key equipment in the production process of shock absorbers for vehicles, railway vehicles and other vehicles. So far, domestically developed shock absorber test benches all use crank-link mechanism as the generator of sinusoidal vibration excitation (see Chinese patent 95226272.X, 200820160048.9). Theoretically, a crank linkage cannot produce sinusoidal motion. [0003] The crank-link mechanism is widely used as the vibration excitation mechanism in the shock absorber test bench because of its simple implementation, strong bearing capacity and motion law close to the sinusoidal mechanism. However, the mechanism movement error produced by it has always plagued the test accuracy of the shock absorber test bench, causing th...
