一、引言圆柱形螺旋拉伸和压缩弹簧(下简称弹簧)应用很广。由于弹簧尺寸参数较多,其设计计算比想象的要复杂,生产现场中常不经计算而凑合使用;又因现有资料上的设计方法多沿袭过去,所得尺寸往往不注意符合新公布的国家标准。为此,本文提出一种以国标为基础的简易方法,以利实用并促进弹 I. Introduction Cylindrical helical tension and compression springs (hereinafter referred to as springs) are widely used. Because the spring size parameters are more, the design calculation is more complex than imagined, the production site is often used without any calculation; and because of the existing data on the design method followed many times, the resulting size often do not pay attention to meet the newly published national standards . To this end, this paper presents a simple method based on the national standard, to facilitate the practical and to promote the bomb
