摘　　要：对某折叠翼所采用的金属橡胶缓冲器的设计参数进行了研究。本文采用准静态接触有限元分析与ADAMS动力学仿真结合的方法,将刚体动力学接触碰撞刚度与有限元接触刚度相融合,确定了等效的缓冲装置线弹性材料参数,最后得到了不同驱动力与缓冲装置组合下折叠机构展开到位的冲击载荷,可为展开机构设计及缓冲装置工程研制提供参考。After researching for overall characteristics of metal rubber buffer analysis, this thesis defines the equivalent elastic material parameters of the metal rubber buffer by combining the quasi-static contact finite element analysis to ADAMS dynamics simulation and by merging the rigid body dynamics contact collision rigidity with finite element contact rigidity. Ultimately, the impact load under different driving forces and metal rubbers combination is obtained when the folded-wing deploys to expected position, which provides reference for design of deploy mechanism and buffer engineering.
