并联机构的运动动力学和运动精度在很大程度上取决于典型刚性连杆的重量和刚度。因此,这些部件的设计应该是轻便但坚固的。利用拓扑优化和尺寸优化技术对两种典型的并联机床刚性连杆机构进行了设计,得到了适用的结构形式。建立了计算模型,提出了一种新的求解拓扑优化问题的算法--引导权重法。使用商业软件Ansys进行尺寸优化。
The motion dynamics and accuracy of parallel kinematic machines largely depend on the weights and rigidity of typical rigid links. Therefore, these parts should be designed in such a way that they are light but rigid. This work employs the techniques of topology and size optimization to design two typical rigid links of a parallel kinematic machine (PKM) and subsequently obtains applicable structures for them. The calculation models are established, and a new algorithm called the Guide-Weight method is introduced to solve topology optimization problems. The commercial software Ansys is used to perform size optimization.
