摘要:
为了研究副车架弹性模量变化对整车性能的影响,对某一款轿车的副车架在保证强度的前提下,进行了模态分析得到其柔性文件,并组装得到了刚柔耦合整车模型。通过patran软件赋予了副车架几组不同的弹性模量,在ADAMS/Car软件中建立了具有不同弹性模量副车架的整车模型,并对它们进行了同等条件下的平顺性及操纵稳定性对比分析,研究了不同弹性副车架对整车行驶平顺性以及操纵稳定性的影响。结果表明,过度提高或者减小副车架弹性模量均会导致驾驶员座椅地板处总加权加速度均方根值上升,使得整车平顺性能下降,且对操纵稳定性也有一定的负面影响,副车架弹性模量维持在一定范围之内可使得整车性能最佳。
Abstract:
In order to study the influence of the subframe elastic modulus change on vehicle performance,on the premise of ensuring the strength,the subframe modal analysis of a car is carried out and its flexible file is obtained,and the rigid-flexible coupling vehicle model is assembled. Using a patran software to give the several group subframes different elastic modulus,this paper establishes vehicle models in the ADAMS/Car software with different modulus of elasticity of the subframe. The ride comfort and handling stability are comparatively analysed under the same conditions. The results show that over-raising or reducing the elastic modulus of the subframe can increase the value of the total weighted root mean square acceleration on the floor of the driver’s seat,resulting in a decrease of the ride comfort of the vehicle and a certain negative impact on handling stability. The elastic modulus of the subframe should be maintained within a certain range to obtain the best vehicle performance.
