高擬真電動巴士與商用車動態模型 2023/07/12

高擬真電動巴士與商用車動態模型
簡介 Introductions

以多體動力學方法搭配目標車數據量測建立車輛動態模型。應用電腦輔助工程(CAE)軟體建立目標車前後軸模板,藉由量測取得懸吊與轉向機構硬點、懸吊零部件特性以及整車重量/慣量/重心等參數並匯入軟體,確保車輛模型具備高擬真與高可靠度。

The vehicle dynamic model was created by the multi-body dynamics (MBD) method and target vehicle data measurement. Templates of front and rear axle were built with computer aided engineering (CAE) software. Parameters such as hard points of suspension and steering mechanism, characteristics of suspension components and weight/inertia/center of gravity were obtained through measurement then imported into software; thereby, ensuring that the vehicle model meets high levels of fidelity and reliability.
