摘　　要：用改进的Taguti方法对已知应力或强度函数关系式的系统或零件进行可靠度估计 ,可得到与计算机仿真几乎同样的结果 ,但计算却非常简单 ;并且 ,还提出了利用计算可靠度的数据对应力或强度的概率密度函数进行拟合的方法 。The modifying Taguchi's method is used in reliability estimation for the system or the component which the functional relationship of its stress and/or strength is known.the reliability calculated with the method is almost the same as that computed with computer simulation method,but the calculation of modifying Taguti's method is simpler.Moreover the methods to fit the pdf of stress and/or strength with the reliability data is also proposed in the paper which are important in ebgineering applications.
