| 抄録 | 懸架ばねの腐食耐久性には種々の要因が絡んでいるため，懸架ばねメーカ各社での試験方案は多々あり，統一化が望まれていた。本委員会では，理論的考察と腐食耐久試験を行って，残存耐久試験から求められるき裂長さの大小により，腐食耐久性を相対的に評価する方法の提案を行った。 |
| Abstract | There were many evaluation methods of corrosion fatigue endurance properties of suspension springs, depending on spring manufacturers, as many factors affect the properties. Therefore, it has been desired to standardize the evaluation methods. This committee performed theoretical studies as well as experiments on corrosion fatigue. A new evaluation method is recommended on the basis of the experimental results that crack length evaluated from residual fatigue life is a good parameter to compare corrosion fatigue performances of suspension springs relatively. |
