| Abstract: | Various performance tests of valve springs of engine STEYR made of spring steel 67CrVA are carried out.It is shown by the tests that the fatigue life and the load lost ratio of the valve springs treated by appropriate peening and hot high pressure process are both meet requirements of the corresponding standard;and it is shown by the relaxation tests that spring steel 67CrVA is a kind of material with good anti-relaxation performance and fatigue performance.In the end,complete engine tests are also carried out and it is shown by the 1 000 h rig test that performance of the valve springs made of spring steel 67CrVA meet the requirements of the standard QZZ1118-1994. |
