基于ANSYS Workbench的牛头刨床机构刚柔耦合动力学仿真分析

Rigid-flexible coupling dynamics simulation of driving mechanism of a shaper based on ANSYS Workbench

应用ANSYS Workbench软件中的Transient Structural模块对牛头刨床机构进行了刚柔耦合动力学分析,得到了将导杆和连杆作为柔性体的刨床机构的运动特征曲线和切削阻力作用下的导杆与连杆的最大应力随时间变化的曲线.这种方法实现了在同一软件平台中进行刚柔耦合机械系统的运动学分析和动力学分析.

The rigid-flexible coupling dynamics simulation of driving mechanism of a shaper is conduc- ted by means of the transient structural module of ANSYS Workbench software in the paper. In the process of the FEM calculation, the guide-bar and the connecting rod are set as flexible bodies. As the results, the curves of kinetic feature of the shaper is obtained, so are the curves of maximum stress o- ver time, showing the maximum stress of the guide-bar and the connecting rod under the action of cutting resistance. By this means, the dynamics simulation of a rigid-flexible coupling mechanical system can be solved with the same software.
