【摘要】：针对溢流阀在线检测系统中,锥阀芯材料为紫铜时,阀芯力学性能不满足设计要求的问题,提出通过优化部分机械结构参数,进而提升阀芯力学性能的研究方法。设计了一种基于均匀设计试验法的阀芯力学性能的仿真试验方案,借助于有限元法、均匀设计试验、动态响应模型等研究方法,分析了各参数对结构优化影响的敏感度,求解了多指标函数与结构参数之间的动态响应模型。最后,利用指标图谱和遗传算法对结构参数进行了优化计算,对比了均匀设计试验法和指标图谱法的优化结果。结果表明,均匀设计试验和指标图谱优化结果十分接近,均匀设计试验法适用于阀芯力学性能的优化设计。
[Abstract]:Aiming at the problem that the mechanical properties of the valve core do not meet the design requirements when the cone valve core material is copper in the on-line inspection system of relief valve, the optimization of some mechanical structure parameters is put forward. A simulation test scheme based on uniform design test method is designed to improve the mechanical properties of the spool. By means of finite element method, uniform design test, dynamic response model, etc. The sensitivity of each parameter to structural optimization is analyzed, and the dynamic response model between multi-index function and structural parameter is solved. Finally, the structural parameters are optimized by using index map and genetic algorithm. The optimization results of uniform design test method and index map method are compared. The results show that the uniform design test method is very close to the index map optimization result, and the uniform design test method is suitable for the optimization design of the mechanical properties of the valve core.
