摘　　要：以ADINA软件的流固耦合求解器为计算平台,对液压滑阀进行数字模拟。分析滑阀内部流场特性、稳态液动力产生原因,研究入口速度和开口度对稳态液动力、阀芯等效应力的影响。研究结果有助于认识滑阀式换向阀的内部流场特性、稳态液动力的产生原因及变化规律和阀芯应力分布情况,并对滑阀结构参数设计和性能优化起到一定的指导作用。The digital simulation of the spool valve was carried on using the solver of ADINA. The inner flow field of the spool valve and steady fluid power were analyzed. The influences of inlet speed and openness on steady fluid power and valve core equivalent stress were studied. The research helps to know the internal flow field characteristic of spool valve, the production reason and change rule of steady-state fluid power and the stress distribution of the valve core. It offers guidance for the structural parameters design and performance optimization of spool valve.
