Taking the low-speed damping characteristics of the valve plate type hydraulic shock absorber as the research object,through the analysis of the working principle and structure characteristics,it was deduced the clearance leakage was the reason for so large difference between the test data and design value as to the low-speed damping characteristics.By comparison with the damping characteristics data before and after improvement on structures,the optimal combination structure with low-speed damping characteristic was gotten,which could offer reference for the study of the high-speed damping characteristics of the shock absorber late.
