摘　　要：多工位料机在自动化加工生产线和装配线中被广泛应用,针对其旋转部件因质量较大导致旋转惯量大、驱动源所需扭矩增加,进而额外增加成本以及系统功耗的问题,该文通过拓扑分析进行全方位优化,以实现多工位料机旋转部件的轻量化。首先分别对旋转部件中的工装板、基准板和旋转盘进行静应力分析,在满足静应力各项条件的基础上再分别对他们进行拓扑分析;然后根据拓扑分析结果进行零件的重构及轻量化优化设计;最后再次对重构的零件进行静应力分析。结果表明,在满足静应力的基础上,通过拓扑分析进行轻量化优化设计可有效降低旋转部件总质量及旋转惯量,总质量降低了18.5%,这对于降低成本及系统功耗具有重要意义。The multi-station feeder has a wide range of applications in automatic processing production lines and assembly lines.In view of the problem that the rotating parts of the multi-station feeder have large mass in the rotating motion,resulting in large rotational inertia,and increase in the torque required by the driving source,which in turn increases the additional cost and system power consumption,the topology analysis is used to optimize the rotating parts of the multi-station feeder in an all-round way so as to realize the lightweight optimization of the rotating parts of the multi-station feeder.Firstly,the static stress analysis of the tooling plate,the reference plate and the rotating disc in the rotating part is carried out respectively.On the basis of satisfying the conditions of static stress,the topological analysis of them is carried out respectively.Then,according to the results of topological analysis,the parts are reconstructed to carry out lightweight optimization design.Finally,the static stress analysis is carried out for the reconstructed parts.The final results show that on the basis of satisfying the static stress,the lightweight optimization design through topology analysis effectively reduces the total mass of the rotating parts by 18.5%,which can significantly reduce the rotational inertia and is of great significance for reducing the cost and system power consumption.
