针对目前我国脐带连接器存在的不足,对火箭自动对接脱落低温连接器进行研究。研究分析火箭连接器3-PSS机构的运动学特性,在推导其机构运动学正、反解数学方程的基础上,应用Matlab/Simulink仿真分析活塞杆与动平台中心点的运动学关系。结果表明:3-PSS机构能实现连接器的对接动作,满足设计的区域空间要求。
Aiming at the shortcomings of umbilical cord connector in our country, the research on the low temperature connector of rocket auto-docking and falling off is carried out. The kinematics characteristics of the rocket connector 3-PSS mechanism are analyzed and analyzed. Based on the kinematics positive and inverse mathematical equations of the mechanism, the kinematic relationship between the piston rod and the center of the moving platform is analyzed by Matlab / Simulink. The results show that the 3-PSS mechanism can achieve the docking action of the connector and meet the design requirements of the regional space.
