机械零件设计计算中避免试算的方法探讨

A Procedure Avoiding Tryerror in Design Calculation for Mechanical Elements

提出了机械零件设计计算中避免试算的一种简单实用方法——待求参数有效值的直接计算查表法的基本原理，并对普通螺栓联接的疲劳强度、静强度和弹簧强度等的设计计算待求参数有效值的表达式以及参数表进行了探讨，最后用实例说明了这种方法的简洁与有效．

A simple and useful procedure avoiding tryerror method in design calculation of mechanical elements is described. At first, form the effect value of the required parameter by putting all the related parameters with required parameter in the original formula, then calculate it directly, and through the table about the relation between the required parameters and its effect values, the required parameter can be determined easily at last. By examples about bolts and springs, the procedure is explained.
