伺服驱动控制器的MTBF实用计算法

A Practical MTBF Calculating Method of Servo Controllers

介绍了采用元器件计数预计法的伺服驱动控制的平均故障间隔时间(MTBF)实用计算方法。通过引用国内外公布的常用元器件通用失效率,对一款伺服驱动控制器的MTBF指标进行计算。方法简单方便,效果良好。

The paper introduces a practical method to calculate the mean time between failures（MTBF） of AC servo controllers,using the components counting prediction method.A servo controller MTBF referring to the components failure rates published in foreign and domestic countries was calculated.This method is simple and can get a good result.
