摘要
提出了在结构可靠性设计中,根据现有加工条件和设计要求确定几何尺寸变差系数的思想,并给出了当已知精度等级时,直接加工尺寸和组合尺寸变差系数的计算方法和程序。采用该方法使可靠性设计更切合实际。
A method of how to decide the size coefficient of variation in the structural reliability design is put forward.The calculation method and program of directly manufacturing sizes and grouping sizes are given when the accuracy grade is known. In a word, this method makes the reliability design more practical.
