| 摘 要： | 研究了一种双腔双阻尼的被动式自适应缓冲器;给出了此缓冲器的数学模型,并基于动力学仿真软件ADAMS建立了该缓冲器的虚拟样机;分析了该缓冲器的着陆动态性能及其主要参数对全机着陆动态性能的影响.分析表明:在使用功条件下,自适应缓冲器的着陆性能比单腔变油孔缓冲器性能略好;而在粗暴着陆条件下,自适应缓冲器的过载远小于单腔变油孔缓冲器,起到主要减载作用.增大高压腔、低压腔体积或增加低压腔压力或减小高压腔压力均可使自适应缓冲器的过载减少.

| Abstract: | A new passive adaptive shock absorber of the landing gear with double-cavity and dual-damping is studied.Its mathematical model and the virtual prototype are established based on the dynamics simulation software ADAMS.The landing dynamic characteristics and the effect of the parameters on the proposed adaptive shock absorber are analyzed.The results show that the proposed adaptive shock absorber has the slightly better landing performance at the normal load case and much less overload at the crudely landing... |
