【摘要】：【目的】改善病死猪搬运车的工作性能,降低成本,对其转盘结构进行多目标优化设计。【方法】采用Creo Simulate三维设计软件,对病死猪搬运车的转盘结构进行了静力学有限元分析以及灵敏度分析,建立多目标优化设计模型。采用模糊物元分析法和加权平均法对设计方案进行优选。【结果】建立了优化设计数学模型,得到了6组非劣解;通过评估优选,获得了病死猪搬运车转盘结构的最优化设计方案。优化设计前后的参数对比分析结果表明,优化后的病死猪搬运车转盘质量为20.90 kg,比原始方案(25.94 kg)减小了19.43%;最大等效应力为1.44 MPa,比原始方案(1.50 MPa)减少了4.00%。【结论】基于灵敏度分析的病死猪搬运车转盘结构多目标优化设计是可行的,可以为转盘结构的改进提供理论指导。
[Abstract]:[objective] to improve the working performance and reduce the cost of the sick and dead pig truck, and carry out multi-objective optimization design of its rotating disc structure. [methods] Creo Simulate three-dimensional design software was used. Static finite element analysis and sensitivity analysis of the turntable structure of the dead pig truck are carried out. A multi-objective optimization design model was established. The fuzzy matter-element analysis method and the weighted average method were used to optimize the design scheme. [results] the mathematical model of optimal design was established, and six groups of non-inferior solutions were obtained. The optimum design scheme of the turntable structure of the dead pig truck is obtained. The results of comparison and analysis of the parameters before and after the optimization design show that, The optimized turntable mass of sick and dead pig truck is 20.90 kg, which is 19.433.The maximum equivalent stress is 1.44 MPA, which is 4.00 kg less than that of the original scheme (25.94 kg). [conclusion] based on sensitivity analysis, the turntable structure of sick and dead pig truck is more than that of the original one. Objective optimization design is feasible, It can provide theoretical guidance for the improvement of turntable structure.
