      摘要
    • 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 of dead pig vehicle and cut down the costs, multi-objective optimization design was carried out on the structure of turntable.
      Method  By using the Creo Simulate three-dimension design software, the statics finite element analysis and sensitivity analysis of the original turntable were executed．Based on the above analysis, a multi-objective optimization design model for the structure of turntable was built．The optimal design scheme was selected using the fuzzy matter-element analysis method and weighted average method.
      Result  The multi-objective optimization design model for the structure of turntable was built, and six groups of non-inferior solution were obtained. The optimal design scheme was obtained by evaluating and preferring. Comparative analysis on parameters before and after optimization showed that the turntable mass after optimization was 20.90 kg and reduced 19.43%. The maximum equivalent stress was 1.44 MPa and reduced 4.00%.
      Conclusion  The proposed structural optimization design for the turntable of dead pig vehicle based on sensitivity analysis is reasonable and feasible. The result can provide the theoretical guide for improving turntable structure.
