摘　　要：直线电机驱动珩磨机床往复运动可以提高运行速度、换向加速度和定位精度,提高珩磨质量和效率。直线电机垂直应用的关键问题之一是直线电机在运动中意外失电,直线电机动子的安全保护问题。针对此问题,设计了一种气动抱闸保护装置。通过对直线电机运动系统的力学分析,建立了直线电机的数学模型,并对安全保护装置下直线电机失电后动子的运动状况进行了计算分析。结果表明,该气动抱闸装置具有很好的刹车效果,并且该气动抱闸装置也适用于直线电机垂直应用的其它场合。Linear motor driven reciprocating motion of honing machine can improve the running speed,reversing acceleration and positioning accuracy,and improve the quality and efficiency of honing. One of the key problems of the vertical application of linear motor isthe security protection problems of linear motor when it has a situation of unexpected loss of powerin motion.A pneumatic brake system was designedto solve this problem. By analyzing theforce of linear motor motion system,the mathematical model of linear motor was establishedand the motion condition of linear motor after the unexpected loss of power was calculated and analyzed. The results showed that the pneumatic brake system had a good braking effect and itwas also applicable to other situation that the linear motors werevertical applications.
