摘要
首先对滑鞍进行受力分析,然后通过有限元分析软件ANSYS Workbench对两种不同形式滑鞍进行静力学分析对比,最后采用拓扑优化和尺寸优化相结合的方法对龙门加工中心滑鞍进行优化设计。结果表明经过优化后的滑鞍质量减轻了227.8 kg,相比原结构质量减轻15.32%,最大变形量减小了0.241 6μm,相比原结构最大变形量减小9.94%,同时动态特性略有提高,为滑鞍的优化设计提供了一种新思路。
Firstly,the stress analysis is carried out,then the comparison of the static analysis of two different forms of sliding saddle are carried out by the finite element analysis software ANSYSWorkbench,the optimization design is carried out at last by using the method of topology optimization and size optimization. The result indicates that the quality of sliding saddle is reduced by 227. 8kg after optimization and is reduced by 15. 32% compared with the original structure. The maximum deformation is decreased by 0. 241 6μm and is decreased by 9. 94% compared with the original structure,at the same time,the dynamic characteristics are increased slightly and provide a new idea for the design of sliding saddle.
