Characteristic simulation of telescopic shock absorber

According to the throttle slice thickness and pre-deformation of throttle slice, the velocity points of valve opening were analyzed by the relation of flux to the velocity, and the analytic formulas of shock absorber velocity when valve opening were given. Based on this, the outer characteristic model of shock absorber was established by piecewise linear function. A practical example of simulation of shock absorber outer characteristic was given, and the performance test was conducted. The results show that the model of outer simulation is correct, the simulation values is coincide with test values, and it has important reference value for telescope shock absorber design and characteristic analysis.
