چکیده انگلیسی
A life-stress model for cylinders was built based on wear fault mechanism, and the test scheme was optimized using temperature, pressure and velocity as acceleration stresses. An accelerated life test for cylinders was designed and implemented. Life eigenvalues at different stress levels were acquired and analyzed. Undetermined parameters of acceleration model were estimated, and life indices under normal stress condition were extrapolated and compared with those from normal stress test. The feasibility of the optimization scheme and the correctness of the acceleration model were verified. Compared with twin-stress accelerated life test for cylinders, the test period was further shortened.
