Article Preview

The approach to estimating the life-stress model and the model parameters for X-series hydraulic cylinders was studied, and the theories and statistical methods related to the reliability index under normal stress were reproduced precisely through the accelerated life test. With temperature and velocity as the accelerated stress, the accelerated life test for hydraulic cylinders was implemented, and data acquisition was conducted. Statistication, assessment and transformation were performed on the test data with statistical models related to the theory. The transformation results of the reliability information from the accelerated life test reproduced precisely the reliability index of hydraulic cylinders at the temperature of 308K and the velocity of 0.25m/s (normal stress), and the test period was shortened to one fifth.
