Determination fo No-Failure Test Times for the Life Test of Hydraulic System Components

It is very important for the manufacturers to predict the life of hydraulic system components according to the results fo life tests. Since it takes too much time to test the hydraulic system components until fuilure, the no-fuilure test method is applied for the life test of them. If the shape parameter of Weibull distribution, the number of samples, the confidence level, and the assurance life are given, the no-fuilure test times of hydraulic system components can be calculated by given equations. Here, the procedures to obtain the no-fuilure test times of the hydraulic system components such as hydraulic motors and pumps, hydraulic cylinders, hydraulic valves, hydraulic accumulators, hydraulic hoses, and hydraulic filters are described briefly.
