摘要
滚轮螺母丝杠传动型控制棒驱动机构(CRDM)的主要失效模式是滚轮磨损。以滚轮为研究对象,利用通用的ADAMS仿真软件计算分析滚轮在正常、坑状缺陷及过度磨损状态下的振动信号特性。结果表明:在CRDM工作过程中,会产生明显的冲击信号;随着状态的劣化,冲击信号强度增强。
Abrasion is the primary cause for the failure of the roller screw drive type CRDM. This paper describes a method of CRDM roller state diagnosis based on computer simulation. Through a common simulation software ADAMS, the vibration characteristics of the roller under normal conditions, pit defects and excessive abrasion have been obtained. Research indicates that the roller will have a significant impact signal while working. With the deterioration of conditions, the impact signal will be enhanced.
