摘要:

根据航天机器人太空作业的需要,设计了三臂机器人简化模型,应用D-H方法建立了坐标变换矩阵,推导了该机器人的运动学方程。基于ADAMS虚拟样机技术,分别在三种重力场环境下,对机器人的爬杆过程进行仿真,得到了机械手攀爬过程受力曲线,分析了影响机械手夹持力的主要因素,从而为这类机器人的设计提供参考。

关键词: 机器人, 在轨, 仿真, 夹持力

Abstract:

A simplified robot model with three arms was designed according to the needs of space operations. The coordinate transformation matrix was established based on the D-H method and the kinematic  equations of the robot were derived. Based on ADAMS virtual prototyping technology, the climbing process of the robot on a pole was simulated for three kinds of gravity, respectively. The force curves and effect factors were obtained so as to offer the design references for the robot. 

Key words: robot, on orbit, simulation, clamping force
