英文摘要	To improve the shock absorbing performance of UAV landing gear, a cushioning mechanism of articulated landing gear was dynamically analysed and optimally designed. Based on the establishment of mathematic model of UAV ground movement and the stress analysis of landing gear under braking control, the behavior and scheme of the cushioning mechanism were discussed. The software of multidisciplinary design optimization iSIGHT combined with the dynamic software Adams were applied to the optimization of cushioning mechanism. Then, taking the requirements of braking condition and shimmy containment as constraint, the size of the cushioning mechanism and the spring stiffness were optimized by using the method of point-by-point comparing at macrocosm combined with the sequential quadratic programming approach. The taxiing test and stiffness test of the optimized landing gear were carried out. The results show that the compression displacement meets the desired requirement and the efficiency of buffer is increased by 71. 5%. The analysis and optimization methods provide guidance for the design of UAV articulated landing gear.
