摘要

汽车发动机怠速运转时方向盘的抖动严重影响驾驶舒适性，本文利用振动测试与模态分析方法研究方
向盘怠速抖动原因，发现方向盘工作状态模态频率与发动机二阶激励频率相近，从而引起方向盘共振。为降低方向盘振
动，本文提出两项改进措施，包括结构优化和方向盘轻量化设计。最后通过试验验证了改进措施的有效性。

Abstract

Vibration tests and modal analysis method were used to recognize cause of steering wheel’s shaking
under engine idling operation, it was found that the steering wheel’s operating modal was close to engine’s second
order excitation frequency, which caused steering wheel’s idle shaking. Three improvements were presented to relief
this problem, including structural optimization, lightweight design of steering wheel. The effectiveness and rationality
of the improvements was verified through experiments.
