Research on Model of Failure Distribution for Numerical Machine with Random Ending Method
Pei Yong-hong · Systems Engineering - Theory & Practice · 2005
According to the data of random timing ending test, the failure time is obtained by applying total failure time method in this paper. Through Johnson method, the sequence number of failure time is acquired. The empirical distribution function of failure time is obtained by using method of approximate mesoposition order. The model of failure distribution is not the single one , so the optimum distribution model is determined by applying method of chart analysis and error area ratio. By field test data of a certain type numerical machine, a introduction to the whole course of calculation is given. This arithmetic is simple, accurate and valuable to engineering.
