基于ADAMS的汽车悬架-轮胎参数协同优化研究OA

Aiming at the issues of tire wear and vehicle ride comfort during driving,a double-wishbone suspension vehicle was taken as the research object.Simulation models of the full vehicle and suspension system were built using ADAMS/Car,and combined with the PAC2002 tire model,the influence patterns of suspension positioning parameters(such as toe angle)and tire parameters(such as tire pressure and cornering stiffness)on tire wear and vehicle ride comfort were analyzed.Parameter optimization was carried out using the ADAMS/Insight module,and multi-parameter collaborative optimization was achieved through response surface methodology combined with orthogonal experimental design.The results showed that toe angle and camber angle were identified as the core suspension parameters affecting tire wear.Among the collaborative simulations,tire pressure had the greatest influence on vehicle ride comfort.After the combined parameters of tire pressure,cornering stiffness,and toe angle were optimized,the vertical acceleration of the vehicle body was reduced by approximately 15%,tire wear was decreased,and both ride comfort and handling stability were improved.A reference for the collaborative design and parameter calibration of automotive suspension-tire systems was provided by the research results,which have certain engineering application value for enhancing comprehensive vehicle performance such as ride comfort.
