The low voltage breaker is composed of electric conducted system,extinguish-arc room, heat tripper and electric magnetism wink-moved mechanism.The functions of move mechanism directly impact the reliability of breaker's move. This topic is imported by using the exchange module of multibody dynamics simulation software automatic dynamic analysis of mechanical system,and then its movement was simulated by applying ADAMS,with the design and the optimization of DW16 Low-voltage breaker's ususal mechanical movement.

摘 要：低压断路器由导电系统、灭弧室、热脱扣器和电磁式瞬动机构组成，其中操动机构的性能直接关系断路器动作的可靠性，本课题利用Pro/E对操动机构进行三维实体造型，然后将利用多体动力学仿真软件ADAMS进行仿真，完成对DW16型低压断路器的常用操动机构的设计和优化。

Arc-glow plasma depositing technique is a new surface coating method. With the help of vacuum arc discharge, a cold cathode arc source continually emits ion beams of coating elements with high currency density and high ionizing ratio.Upon the ion bombard and diffusion work on, the surfaces of the parts form deposited layers, diffusion layers. In this study, a commercial magnesium alloy AZ91 was coated with Ti film layer.

加弧辉光离子渗镀技术将辉光放电与弧光放电有机地结合起来，利用辉光放电空心阴极效应使工件迅速升温，同时在真空容器壁上设置一个或多个金属阴极电弧靶源，利用真空电弧放电而不断地发射出高能量、高电流密度、高离化率的欲渗金属离子流，依靠扩散和离子轰击作用快速渗入工件表面层，在工件表面可以形成渗层、镀层、渗镀结合层。
