圆柱形螺旋弹簧是各种机械设备中最常用的零件之一,但其标准化程度很差,常常需要自行设计。目前圆柱弹簧的设计方法比较繁复,不易掌握,而且这种计算方法还存在缺点,常易引起设计的失误。本文想就这个问题提出一些改进意见。一、现在采用的设计方法我国螺旋弹簧现有设计方法是五十年代根据苏联造船工业部有关设计资料编制的。这种方法虽然存在一些明显的弊病,但在国内一般教科书和工厂机械设计手册中仍在广泛应用。(1)它首先按一定原则将弹簧分为三类:受动负荷的重要弹簧;受静负荷或负荷均匀增加的弹簧;不重要的弹簧。再从弹簧类别来确定许用应力。这种分类法是不适当的,一方面弹簧的重要性并不是选择许用
Cylindrical helical springs are among the most commonly used parts in a variety of mechanical devices, but their standardization is poor and often requires their own design. At present, the design method of cylindrical springs is complicated and not easy to grasp, and there are some shortcomings in this method of calculation, which often leads to design errors. This article wants to make some suggestions for improvement on this issue. First, the design method adopted now The design method of our country’s coil spring is based on the design information of the Soviet shipbuilding industry department in the 1950s. Although this method has some obvious shortcomings, it is still widely used in the domestic general textbook and factory mechanical design manual. (1) Firstly, it divides the springs into three categories according to a certain principle: the important spring for the dynamic load, the spring for the static load or the uniform increase, and the non-essential spring. Then from the spring category to determine the allowable stress. This classification is not appropriate, on the one hand the importance of spring is not a choice of allowable
