摘　　要：通过对电磁换向阀换向工作时稳态和瞬间液动力的理论分析,建立了稳态和瞬间液动力的理论公式,并进行了定性分析,探讨了液动力对系统的影响,并认为液动力是影响换向失灵、烧毁等现象的重要因素.说明设计系统时应考虑液动力,以使系统设计完善.By the analysis of steady state and transient state hydrodynamic force during electromagnetic directional valve inverting, this article establishes the theoretical formula of steady state and transient state hydrodynamic force The qualitative analysis is done and the influence of hydrodynamic force is also disscussed. This article point outs that hydrodynamic force is the important factor of influencing invertmg malfunction and leading to burning＇. So design system should consider hydrodynamic force and makes design perfect.

关 键 词：电磁换向阀 稳态液动力 瞬间液动力
