Abstract
The factors which affect steering wheel shimmy are briefly introduced in this paper.The causes of steering wheel shimmy are investigated by road reappearance test.Frequency spectrum analysis,coherence analysis and order analysis are applied to locate some defective parts,which are optimized and validated later on.The results show that the steering wheel shimmy is reduced effectively.
