摘要/Abstract

摘要： 传统的阀芯位移稳定性是在系统参数确定的前提下进行的，然而，在实际生产的使用过程中，各种系统参数具有不确定性.针对此问题，建立了一个锥阀工作动态过程的有限元分析模型，采用双向流固耦合和重叠网格方法分析求解压力入口下锥阀的动态响应过程.考虑参数随机性的影响，以阀芯稳定后位移是否超过许用位移量为衡量标准建立阀芯位移波动的极限状态方程，通过Monte-Carlo仿真和Kriging方法，对阀芯稳定后位移的波动情况进行了可靠性分析.研究发现，阀芯稳定位移波动范围小于理论值的19%，阀芯稳定位移的可靠度随着入口压力的增大而降低.

Abstract: The traditional spool displacement stability is carried out on the premise that the system parameters are determined. However， in the process of actual production and use， various system parameters are uncertain. To solve this problem， a finite element analysis model of the cone valve’s dynamic process was established， and the dynamic response process of the cone valve under the pressure inlet was analyzed and solved by the bidirectional fluid-solid coupling and the overlapping grid method. Considering the influence of parameter randomness， the limit state equation of the spool displacement fluctuation was established based on whether the displacement after the spool stabilizes exceeds the allowable displacement. The reliability analysis of the displacement fluctuation after the stability of the spool was carried out by the Monte-Carlo method and Kriging method. It was shown that the stable displacement fluctuation range of the spool is 19% less than the theoretical value， and the reliability of the stable displacement of the spool decreases as the inlet pressure increases.
