基于有限元的摆动臂优化设计
|
摘要
随着工业机器人技术飞速发展,其在电动汽车装配领域应用越来越广泛,但也逐渐暴露出一些问题,如工业机器人质量重、结构复杂等,因此相关研究人员提出将有限元方法应用到机器人优化设计中。在Ansys Workbench中使用Shape Optimization模块对六自由度工业机器人摆动臂进行了优化设计,分别从质量、应力和变形三个方面对优化前后模型进行了对比分析,将数值模拟的方法应用到了优化设计领域,优化结果对工业机器人设计和改进工作具有重要的借鉴意义。
With the rapid development of industrial robot technology, it has become more and more widely used in the field of electric vehicle assembly, but it has gradually exposed some problems, such as industrial robots with heavy weight and complicated structure. Therefore, relevant researchers have proposed to apply the finite element method to robots. Optimized design. In the Ansys Workbench, the Shape Optimization module was used to optimize the design of the six-degree-of-freedom industrial robot swing arm. The three models of quality, stress and deformation were compared and analyzed. The numerical simulation method was applied to the optimization design field.The optimization results have important reference significance for the design and improvement of industrial robots.
