轴强度可靠性算法的误差分析

Error Analysis for Reliability Algorithms Applied to the Shaft Strength

简要介绍了机械零件的可靠性算法，并通过轴的强度计算实例，分别采用中心点法、验算点法以及蒙特卡洛法对轴的疲劳强度进行了可靠性计算，比较了各算法的误差大小，说明了各算法在轴的疲劳强度可靠性计算中的实用性．

In this paper,the reliability algorithms for machine elements are introduced breafly and the reliability of the shaft fatigue strength is calculated by the centre-point,the check- ing-point and the Monte Carlo algorithms respectively.Through the shaft example,the errors of the above agorithms are compared and the practicality of each algorithms for re-liability calculation of the shaft fatigue strength is illustrated.
