Metal springs are used extensively in technical products. The mathematical relationships and Goodman diagrams contained in the DIN EN 13906–1 standard form the essential basis for the design and calculation of cylindrical helical compression springs. They are used not only nationally, but internationally in the spring industry and by spring users. However, the diagrams are more than 50 years old and no longer reflect the current status of modern spring materials and spring manufacturing technologies. This results in great uncertainty for users of the standard, which currently has to be compensated by costly fatigue tests.

基于 FKM 指南“弹簧分析强度评估”的压缩弹簧实用疲劳强度图

金属弹簧广泛应用于技术产品中。 DIN EN 13906-1 标准中包含的数学关系和古德曼图构成了圆柱形螺旋压缩弹簧设计和计算的重要基础。它们不仅在国内，而且在国际弹簧行业和弹簧用户中使用。然而，这些图表已有 50 多年的历史，不再反映现代弹簧材料和弹簧制造技术的现状。这给标准的用户带来了很大的不确定性，目前必须通过昂贵的疲劳测试来补偿。
