動態減震器於車輛舒適性之應用

Application of Dynamic Vibration Absorber for Vehicle Ride Comfort

指導教授 : 尤正吉

摘要


舒適性對於車輛懸吊設計為一重要議題,故本研究將提升舒適性為目標,並且希望幫助業界以更簡單明瞭的方式達到提升舒適性的目的。近年來由於石油枯竭,以及許多的環保意識,電動車的發展逐漸受到矚目,然而為了減少更多的能源消耗,研究出輪轂馬達之電動車,此設計係將馬達安裝於輪胎上簡化車輛傳動系統,此舉雖然使傳動效率增加,卻造成簧下質量過重之影響;為改善此負面效應,在過去的研究中,已經有利用在懸吊中加裝減震質量之概念來吸收輪胎之震動。本研究為過去之延伸,利用兩組質量轉移之動態減震器的雙減震器系統來改善舒適性,而動態減震器可分為簧上質量轉移置簧上、簧上質量轉移置簧下以及簧下質量轉移置簧下等三種型態,前兩者亦可用於無簧下質量過重的車種上,本研究優化動態減震器參數,並以隨機路面下輸入,評估人體加權加速度均方根值之優劣,即可得其舒適性改善程度。本論文之設計可以讓未來動態減震器於車輛懸吊之應用與實現有效給予建議。

The goal of this study is improving the riding comfort, because it is an important issue in vehicle design. The electric vehicles have been noticed because of the oil depletion and rise of environmental consciousness in recent years. However, in order to reduce more energy consumption, there is one kind of electric vehicle called wheel-hub motor vehicle, that means, the energy source-motor is installed in the wheel, so that it can simplify transmission system of vehicle; however, it makes riding comfort poor because the unsprung mass is overweight. To improve this negative effect, some research used the dynamic vibration absorber to absorb the wheel vibration in the past. This thesis used Double-Dynamic vibration absorber which is composed of two kinds of dynamic vibration absorbers to improve the riding comfort. Dynamic vibration absorbers can be divided among three types: transfer sprung mass to sprung, transfer sprung mass to unsprung and transfer unsprung mass into unsprung. Transfer sprung mass to sprung and transfer sprung mass to unsprung can also be used in vehicle with no overweight unsprung problem. This research optimizes the dynamic vibration absorber parameter, and then evaluates the effect of random road input on human body weighted acceleration R.M.S value, so that it can get improvement of the riding comfort. The conclusion of this thesis can give suggestions for application of vibration absorber on vehicle suspension in the future.
