摘要:

为研究柔性关节机器人运动状态下的振动特性,提出一种机构振动环境预测新方法. 以3自由度单臂机器人系统为研究对象,将结构中的行波理论与机器人关节旋转变换矩阵相结合,通过各结点力平衡及位移边界条件,建立机构系统在运动状态下的环境预测模型. 对运动状态下的机器人系统进行振动实验,结果表明本文方法可行.

Abstract:

A new approach of vibration environmental prediction on mechanism is presented to study the vibration characteristics of moving flexible joint robot. Taking a 3-D manipulator robot as the research object, this method combines wave theory of structures with rotated transform matrix of joint. Considered the general force balance and displacement boundary of each joint, the environmental prediction model of system in moving states is established. Vibration experiments on moving robot are done. It is shown that the approach is feasible.
