摘要


惰速方向盤振動是顧客評估汽車動態特性中一項極為重要之指標。本文主要即針對惰速方向盤共振問題,以實驗模態分析方法進行偵錯改善,並建立有限元素模式,分析其結構之模態特性,做為結構修改上之依據。經由本文之討論,我們可得知增加方向機柱支架及方向盤輻條之勁度與減輕方向盤外環之重量,對提高方向盤自然振頻有很大的助益;此外亦提供了一個有效的分析模式,可做為往後新車型設計之參考。

An approach for the reduction of the steering wheel vibration, occurring at engine idling, is described. The reduction of the vibration can be achieved by increasing the resonant frequency of the steering system, which is constructed of a steering wheel, steering column, its support member and so on. In this paper, an experimental modal analysis to clarify the resonant phenomena and an eigenvalue analysis with FEM to suggest practical hardware modifications are discussed. We have found that the approach introduced here can be applied to conceptual primary design of steering system.
