基于ANSYS Workbench的顶驱提环侧连接板的拓扑优化设计
|
摘要
针对经验设计方法中顶驱提环侧连接板存在质量偏重、外型不尽合理的问题,将连续体拓扑优化理论引入顶驱提环侧连接板的设计中,在设计空间内建立了最大范围设计模型,应用ANSYS Workbench进行了求解,通过两次拓扑优化将质量在最大设计空间内进行了最为合理的分布,摆脱了传统优化设计在原设计基础上优化的思路,克服了传统优化在优化初始排除最佳方案的可能性。根据拓扑优化结果并综合考虑了装配条件、加工制造费用等因素建立了侧连接板模型,分析了优化后侧连接板形变和应力的分布情况。结果表明该方法设计出的侧连接板完全满足实际需求,证明了该方法的可行性和合理性,为顶驱侧连接板的设计提供了新的思路和参考,为降低顶驱生产成本和整机重量,提高顶驱市场竞争力提供了可能,具有重要的实际经济意义。
Aiming at the overweight quality and unreasonable appearance of side connecting plate,which is designed according to experience design method,the theory of topology optimization design of continuum structure is introduced into the design of the side connecting plate. In the design space,the maximum range design model is established and the optimization design is solved by ANSYS Workbench. The most logical distribution is carried out in the maximum design space after two topological optimizations. The method gets rid of the thought of the traditional optimization based on original design and the possibility of elimination of the optimal scheme at the beginning of traditional optimization method. The model of side connecting plate is established after comprehensive consideration of assembly conditions and manufacturing cost. The distribution of deformation and stress of the side connecting plate after optimization is also analyzed. The results demonstrate that the side connecting plate designed by the method satisfies the actual demand. The practicability and rationality is also proved. The method offers a new thought and reference for side connecting plate of top drive. Besides,it also has important practical and economic significance to reduce the production cost and the total weight of top drive,consequently the market competitiveness of top drive is enhanced. The method is provided with the actual economic significance.
