An reliability assessment method based on bootstrap
Jun Wu · Machinery Design and Manufacture · 2010
The middle or small samples of fatigue performance data from mechanical system reliability analysis experiment can not meet the requirements of capacity in traditional statistical method. The Bootstrap method is adopted to calculate the matrix-percentile lower limitation of confidence level. A semi-parameter Bootstrap method is proposed to calculate the reliability lower limitation of confidence level for normal distribution variables. An example of reliability analysis for the servo drive system of CNC equipment is introduced to validate the feasibility of the methods.
