摘要
三自由度喷涂执行器中的转动臂是主要受力零件,对其进行结构优化设计可提高其稳定性和动态特性。首先对转动臂的结构和受力进行分析,然后利用ANSYS Workbench对转动臂进行强度分析,最后利用拓扑优化和模态分析相结合的理论方法对转动臂进行了结构改进。对比优化前后的分析结果,证明优化后的转动臂在结构强度、质量和抗振性能方面得到显著改善,验证了优化结构的可行性。
The rotating arm in the three-degree-of-freedom spray actuator is the main force-bearing part,and its structural optimization design can improve its stability and dynamic characteristics.Firstly,the structure and force of the rotating arm are analyzed.Then the strength analysis of the rotating arm is carried out by ANSYS Workbench.Finally,the structural method of the rotating arm is improved by the combination of topology optimization and modal analysis.Comparing the analysis results before and after optimization,it is proved that the optimized rotating arm significantly improves the structural strength,quality and anti-vibration performance,and verifies the feasibility of optimizing the structure.
