| 摘 要： | 文中研究了一种高轴向刚度三轴转动柔性铰.提出了采用有限元技术对该柔性铰进行弯曲刚度、扭转刚度和轴向刚度分析的原理及方法.在此基础上,对高轴向刚度三轴转动柔性铰的各向刚度进行了有限元分析计算,建立了高轴向刚度三轴转动柔性铰的各向刚度随柔性铰关键结构参数变化的二次拟合方程.研究结果表明,高轴向刚度三轴转动柔性铰不仅各向弯曲刚度相等,而且具有较高的轴向刚度,能实现三轴转动.另外,各向刚度值随关键结构参数变化的二次拟合曲线和实验曲线的最大拟合误差不超过3.50%,各向刚度随柔性铰关键结构参数变化的二次拟合方程能准确预测柔性铰的各向刚度.该研究工作为高轴向刚度三轴转动柔性铰的开发与设计提供了一种有效的方法.
