【Abstract】 Using the method of regression analysis and hypothesis testing, the distribution model of the forepart faults internal time is found. The probability density functions, the distributing function and failure function of forepart faults internal time of horizontal machine center are also calculated. The failure curve of the horizontal machine center during the forepart fault is degressive, the internal time is Weibull distribution.更多还原
