high-frequency fatigue properties of vanadium-containing silicon -manganese 35SiMnVB spring steel
as well as the process performance and fatigue life of the plate spring assembly for a certain auto model and the commonly used 60CrMn steel were studied and tested. The comparison shows that 35SiMnVB steel has good strength-toughness matching
higher high frequency fatigue life and better process performance than that of 60CrMn steel
and the fatigue life of the bench is more than 150 000 times to meet the technical requirements of rear leaf spring assembly of a auto model.
