摘要
本文针对裂解气阀两种阀体结构(米字形阀体和井字形阀体)进行优化,比较两种阀体结构的优化结果。基于ANSYSWorkbench平台对阀体进行结构分析,以阀体等效应力最大值为参考依据,进行了多个对阀体等效应力分布情况有影响的参数的优化分析,确定了其灵敏度及其对应力分布的影响情况,并得到了使阀体等效应力最优的结构参数值,实现改善阀体性能的目的。通过对阀体结构的优化,既减小了阀体质量,同时又明显降低了阀体应力,达到阀体成本和性能的最优化。在两种阀体结构对比方面,井字形阀体在该使用工况下性能更为可靠。
This paper tries to optimize two kinds of body structures(cross shaped and tic-tac-toe shaped)of cracking gas valve and compares the optimization results of these two structures.The valve body structures were analyzed based on the ANSYS Workbench platform,and several parameters influencing the distribution of equivalent stress on valve bodies were also studied,with maximum equivalent stress on the valve body as a reference,to determine their sensitivity and impact on the stress distribution.Therefore,structural parameters generating the optimal equivalent stress on valve bodies were obtained to improve the valve performance.Optimization of the valve body structure not only reduces the body weight and stress,but also saves cost and achieves better performance.Comparison of the two structures showed that the tic-tac-toe shaped valve body was more reliable in this working condition.
