摘要

往复压缩机气阀是整个机体中故障率最高的部件。针对网状阀的结构和运动特点建立了阀片运动规律数学模型,利用Matlab和Ansys软件对阀片瞬态运动规律及动应力分布进行仿真研究,讨论了气阀弹簧刚度及阀片过渡圆弧弧度对气阀阀片动应力分布的影响。研究结果表明:阀片运动过程中的变形应力大于撞击产生的冲击应力;两段铣薄的弹性臂弹性变形最大,该区域产生最大等效应力;改变弹簧刚度和过渡圆弧弧度可以有效地降低应力值,延长阀片寿命。分析结果对进行气阀优化设计、提高网状阀寿命有重要理论意义。

Abstract

Reciprocating compressor has many moving and damageable parts in which valve is the most frequently damaged component. A mathematical model of the valve movement was established according to its structure and motion characteristics.MATLAB and ANSYS software were used to study the transient motion law and the dynamic stress distribution of mesh valve.Then the impact of spring stiffness and transition arc on valve’s stress distribution was discussed. The results show that the stress generated by deformation is much greater than the impact stress. Maximum elastic deformation occurs in two thin elastic arms in which maximum equivalent stress generated. Changing the spring stiffness and the curvature of the transition arc can effectively reduce the stress and extend the life of the mesh valve. The results of the analysis have important theoretical significance for valve design optimization and the improvement of valve life.
