摘　　要：为了降低航天电磁阀低温气密泄漏的风险,以电磁阀R形活门座为研究对象,在对其数控轨迹多层切削的基础上,建立了电磁阀活门座的曲面数学模型,研究了电磁阀活门座型面的研抛路径和余量去除模型,分析了研抛参数对活门座表面质量的影响并取得了良好的应用效果,消除了电磁阀低温气密泄漏的风险。In order to reduce the risk of low temperature air tight leakage of aerospace solenoid valve,the R-shaped valve seat of the electromagnetic valve was taken as the research object.Based on the multi-layer cutting of the NC track the solenoid valve R-shaped valve seat,the surface mathematical model of the solenoid valve seat was established,the polishing path and residual removal model of the valve seat surface were studied,and the influence of polishing parameters on the surface quality of the valve seat was analyzed.Good application effect has been achieved and the risk of low temperature air tight leakage of solenoid valve has been eliminated.
