Finite Element Analysis of the Valve Spring with Different Engine Speed

Abstract:

Article Preview

The valve spring endures alternate load during work, whose dynamic response is vital to the whole performance of the engine valve system. Finite element analysis of the valve spring is researched in the intake process of an engine during which the engine speed varies from 1000r/min to 5000r/min. The investigation indicates that the equivalent stress achieves maximum when the valve is full open following with spring back to some extent, although some residual stress still exist until the valve closed fully, both the intensity and fatigue life can satisfy design need. The distribution over all intake process appears normal distribution at low speed, the stress oscillates seriously with speed increasing.
