摘　　要：通常螺旋弹簧横向刚度计算的理论值与试验值偏差较大,通过理论推导分析标准BS EN13906-1推荐的计算公式发现:螺旋弹簧计算时的高度对其横向刚度影响较大,同时不同长细比的弹簧依据规范公式计算的偏差大小不一;螺旋弹簧在不同垂向压缩比下,其横向刚度并非是一个常量,呈现一定的相关性。通过引入计算高度及其修正条件,并采用有限元方法和试验验证,表明采用修正方法计算的弹簧横向刚度值与试验值最为接近,最大偏差不超过15%,可以满足工程应用的需要。Generally,there is a large deviation between the theoretical value and the experimental value of the lateral stiffness of the helical spring.Through the theoretical derivation and analysis of the formula recommended by the standard BS EN13906-1,it was found that the calculated height of the helical spring had a great influence on its lateral stiffness.Meanwhile,the deviations of springs with different slenderness ratio calculated according to the standard were different.Under different vertical compression ratio,the lateral stiffness of the spring was not a constant,showing a certain correlation.By introducing the calculated height and its correction conditions,and using the finite element method and test verification,it was shown that the lateral stiffness value calculated by the correction method was the closest to the test value,with the maximum deviation not exceeding 15%,which can meet the needs of engineering application.
