【摘要】：为了优化溢流阀锥阀结构力学性能,提升锥阀工作的可靠性。首先,根据工业过程中锥阀性能的设计要求,分析了原结构参数紫铜阀芯的力学性能。其次,采用控制变量法,研究了单个结构参数对阀芯力学性能的影响特点。然后,针对阀芯锥角、阀座流道和阀座倒角结构,建立了参数化力学仿真模型,借助力学模拟、试验设计和数据处理等技术,以二阶响应面函数描述了多指标优化目标与结构参数之间的响应模型。最后,对系统结构响应模型进行了优化求解,并对优化效果进行了评估分析。结果表明,原结构参数的紫铜阀芯不满足力学设计要求,均匀设计试验法优化方案的优化效果良好,能够大幅提升锥阀芯工作的可靠性。
[Abstract]:In order to optimize the structural mechanical properties of relief valve cone valve and improve the reliability of cone valve, firstly, according to the design requirements of cone valve performance in industrial process, the mechanical properties of the original structural parameters of the radial copper valve core are analyzed. Secondly, the control variable method is adopted. The effects of single structural parameters on the mechanical properties of the spool are studied. Then, a parameterized mechanical simulation model is established for the cone angle of the valve core, the valve seat flow channel and the chamfer structure of the valve seat, with the help of mechanical simulation, experimental design and data processing techniques, etc. The second order response surface function is used to describe the response model between the multi-index optimization objective and the structural parameters. Finally, the structural response model of the system is solved optimally, and the optimization effect is evaluated and analyzed. The original structural parameters of the copper spool do not meet the requirements of mechanical design. The optimization effect of the uniform design test method is good and the reliability of the cone valve core can be greatly improved.
