輪內馬達懸吊機構之全車動態模擬敏感度分析

Sensitivity Analysis of the Suspension Mechanism In-Wheel Motor Vehicle Dynamic Simulation

指導教授 : 鄭榮和

摘要


輪內馬達電動車有著較大的車室空間配置以及更為高效率與節能的優勢,在車輛電動化的發展上,將是一個重要的方向。但目前最主要的問題還是因為簧下質量過大而造成操控性與乘適性的不佳。本研究將應用動態減振原理透過輪內馬達相關文獻與機構設計之概念,在並聯式懸吊系統為基礎下,建立ADAMS View分析軟體之全車CAE模型。由於能夠更真實的模擬輪內馬達機構與懸吊系統的作動,因此可以得到更為準確的實際分析情形。全車模型比起四分之一車或二分之一車模型之三維運動,可提供更多包括轉向在內六個維度(向前、側向、垂直、側傾、俯仰、橫擺)的各項資訊。全車CAE模型乃透過雙A臂懸吊將輪內馬達系統與車體作聯接,經本研究所發展之懸吊係數試算工具,以提供全車動態模擬分析時設計參數的設定。最後藉由在各測試條件下作敏感度分析,找出各動態特性取向之主懸吊與第二懸吊彈簧係數和阻尼係數的調整方向,期望能夠對動態減振輪內馬達的全車設計有其參考的價值。

並列摘要


The in-wheel motor electric vehicle has a large car room space allocation, as well as more high-efficiency and energy saving advantages. It is an important direction in the development of vehicle electrification. The main problem unsprung mass is too large, resulting in poor handling and ride comfort. The research will apply the dynamic vibration absorbers theory through the literature of the in-wheel motors, mechanical design concept and the parallel suspension system to build the full vehicle CAE model through ADAMS View analysis software. More realistic simulation of the in-wheel motors agencies and the suspension system, so you can get a more accurate analysis of the situation. The full vehicle model can provide more, including the steering and six dimensions (forward, lateral, vertical, roll, pitch, yaw) of the information than the fourth car or three-dimensional motion of the half car model. To establish the full vehicle CAE model is to connecting the in-wheel motors from the vehicle through the double A-arm suspension. The suspension coefficients spreadsheet tool developed in this study in order to provide a set of dynamic simulation analysis of the full vehicle design parameters. Finally, by the sensitivity in the test conditions to make an analysis to identify the dynamic characteristics of orientation of the main suspension and the second suspension spring and damping coefficients of adjustment direction, I look forward to this study, the reference value in-wheel motor vehicle design.
