L型麦弗逊前悬架横向稳定杆对整车性能影响研究

Study of Vehicle Performance Affected by L-type Macpherson Front Suspension Anti-roll Bar

在ADAMS/Car中应用铁木辛柯梁力学模型建立了某微型电动汽车前横向稳定杆的精确模型及其它各个子系统的动力学模型。运用对比分析的方法,将该车多体动力学模型与ADAMS/Car共享数据库中的整车模型进行试验对比,验证所建动力学模型的可行性和有效性。以该模型为研究基础,探究横向稳定杆对L型麦弗逊前悬架的定位参数及整车侧向特性、纵向特性的影响。

Based on Timoshenko Beam mechanical model in ADAMS/Car, an accurate anti-roll bar model of a mini electric car is established and the other system is also established with ADAMS/Car.In order to prove the correctness of the dynamic mini electric car model, the method of comparative analysis is used between the multi-body dynamics model and the vehicle modelinADAMS/Car shared database. Then the paper studies the effects of anti-roll bar on wheel alignment parameters, body trim and roll.
