Abstract:

The state-equation method in "modern Control" has been used to simulate the dynamic responses of a hydropneumatic shock absorber of aircraft or vehicle. Based on the computer simutation, the relations between the dynamic response of the systems and the structure parameters have been revealed. Therefore, it is a successful attempt for CAD techniqhue in component design of aireraft and vehicle. The time domain analysis of a hydraulic shock absorber such kind of non-linear discontinuous system is successfully carried out, through solving differential equations with "state equation method" and Lonqe-Kutta numerical integrity

Key words: Hydro-pneumatic shock, Dynamic responses, Computer Simulation
