摘要
同时考虑了起落架缓冲系统性能对飞机着陆和滑行过程中的影响,从改善飞机地面滑行动态响应特性出发,在满足着陆撞击等约束条件下,提出并建立了起落架缓冲系统参数优化设计的方法和模型,并以主起落架缓冲系统优化设计为例,具体讨论了优化过程和结果。实例计算表明,利用本文方法将有效地改善起落架缓冲系统性能。
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.
