摘　　要：以某款12m长大客车为研究对象,在Adams/Car中建立双横臂前独立悬架模型,使用双轮同向激振工况进行悬架分析.为减少四轮定位参数变化范围及轮胎磨损程度,改善整车的操纵稳定性,用全因子和响应面法在Adams/Insight模块对现有的双横臂前独立悬架硬点坐标进行优化设计.对优化后的悬架试制并安装在试验样车上进行样车操稳试验验证,对比优化前试验数据发现转向回正和稳态回转的各项评价指标和项目评分都明显改善,验证了优化的可行性和准确性,为后续整车的设计开发作参考.Taking a 12-metre-long bus as the research object,the front double wishbone independent suspension model is established in Adams/Car,and the suspension analysis is implemented by parallel wheel travel condition.To reduce the range of four-wheel alignment parameters variation and the abrasion of tire wear,and improve the vehicle handling stability.The hard point coordinates of the existing front double wishbone independent suspension are optimized by using full factorial design and response surface methodology in Adams/Insight module.The optimized suspension test is tested and installed on the test prototype to verify the experimental verification of operation stability.Compared with the pre-optimization test data,the studies have found that the evaluation indicators and project scores of steering alignment and steady state turning are significantly improved,which verifies the feasibility and accuracy of the optimization.The study would supply a reference for further design and development of the vehicle.
