| 摘 要： | 针对本课题组研制的-JDYP51五坐标虚拟轴混联研抛运动机床,通过建立Pro／E和ADAMS仿真模型,并结合虎克铰和单个支杆的有限元分析,列出了空间刚-柔耦合多体系统动力学方程。仿真实验结果表明,由于机床的铰接特点,支杆在运动中弹性变形很小,其柔性对动平台的轨迹影响不大,可以获得比较稳定的动力学特性曲线。

| Abstract: | A new kind of five-degree virtual axis hybrid polishing machine tool was developed which is made up of "3 axes parallel+2 axes series".Combining with the finite elements of the hook joint and the single leg,an unified dynamics equation of the spatial rigid-flexible coupling multibody systems was built by the simulation model of Pro/E and ADAMS.The result of analysis shows that the elastic deformation of each leg is very small during the movement of the machine and the influence of the flexibility of each leg on the trace of moving platform is not obvious due to the characteristics of joints.Therefore,the stable status of polishing can be obtained. |
