| Abstract: | The influence of the oleo-pneumatic shock absorber on aircraft responser during both taxiing and landing inpact are considered .For improving the dynamic responce characteristics of the aircraft during taxiing,a model and method for optimization of the shock absorber parameters are proposed ,in which the mean square value of the c.g acceleration of the aircraft during taxiing is taken as the objective function and the impact energy to be absorbed as the constraint condition . As an example, the optimization of the main landing gear system is studied based on the model and method proposed above. Because the PSD method is used in the analysis the optimization procedure is easy and simple. |
