Investigation on Shock Pressure Absorbing Approaches for a Hydraulic Vibration Generator
Shock pressure and its absorbing approaches in hydraulic vibration generator for a vehicle body test-bed are discussed in this paper. The principle and characteristics of the hydraulic vibration excitation system are introduced. The main parameters that determine the performance of hydraulic system are calculated and designed. Pressure shocking problem in operation and its absorbing approaches are discussed from theoretical and experimental aspects. An optimal combination of accumulators and common solenoid direction control valve and their parameter configuration and neutral position type selection are obtained in conclusion. Practical usage had approved the feasibility of the design presented in this paper.
