为大型零件的螺栓连接设计的螺栓计算程序,该程序可在PC机上使用,用此程序可使螺栓连接达到最优化;该程序的使用条件:螺栓的使用范围在M4～M39之间、螺栓直径与夹持长度之比L_K/d≤10。其线性计算公式可计算出阻止接合面分离力;非线性计算公式是在工作状态下连接件一侧出现分离或允许出现这种情况下来用;选择四缸汽油发动机上的连接螺栓作为典型实例;计算连杆作用力,在摆角α内,力和扭矩曲线的计算及平面惯性矩的求证;并对计算结果进行评价。
Bolt calculation program for bolting of large parts, which can be used on a PC. The program can be used to optimize the bolting. The conditions of the program are as follows: The use of bolts is in the range of M4 to M39. The bolt diameter And the clamping length ratio L_K / d ≤ 10. The linear formula can be calculated to prevent the joint surface separation force; non-linear formula is in the working state of the connector side appears to separate or allow this situation to use; select four-cylinder gasoline engine bolts as a typical example; Calculate the connecting rod force, in the swing angle α, the calculation of force and torque curves and plane moment of inertia proof; and the calculation results were evaluated.
