Abstract

In the traditional design method, energy absorption efficiency of shock absorber on the landing gear is mainly considered, without fully consideration the effect of the thermal of the shock absorber on its energy absorption efficiency, mechanical properties and structural wear.In this paper, an equivalent mathematical model considering the thermal effect of landing gear is established by taking single acting oleo-pneumatic shock absorber of main landing gear as research object. The combination of multi-body dynamics and Matlab/Simulink method is used. In addition, the effect initial distance of the upper and lower sliding bearings of shock absorber on its mechanical properties and the structural temperature is considered particularly in corresponding parameter sensitivity analysis. The analysis results show that the effect of thermal effect on the comprehensive performance of the shock absorber can't be neglected.
