摘要 ： Abstract
The influence of working condition difference has not been considered in the
traditional reliability modeling of numerical control (NC) machine tools. To
solve the problem, a reliability evaluation method based on mixture variable
parameter power law model (MVPPLM) is proposed in this study. First, the
scale parameter of the PLM is obtained by multi‐dimensional exponential distribution. Second, a proportional relation of failure rate function between each
working condition and reference working condition is established. The proportion coefficient is solved using the partial likelihood
