摘要: 为了满足人们对个性的追求,提出了设计新型运动款汽车的设想.根据整车设计参数及悬架设计理论设计了前双横臂独立悬架;基于ADAMS/View建立了该悬架的虚拟样机模型,对该悬架进行设计研究,通过分析得知,上、下横臂与水平面的安装角度这两个设计变量对悬架的各性能评价指标影响均较大,不仅可以改变变化量的大小,甚至可以改变变化趋势;转向拉杆断开点的位置对车轮前束角的影响很大;对该悬架进行优化设计,优化目标不仅考虑到性能指标的变化量,同时考虑了变化趋势对操纵稳定性的影响, 变化趋势保证了汽车具有不足转向特性和回正特性.优化结果显示所设计悬架系统满足悬架设计要求,悬架的性能指标参数达到了理想的变化范围.

Abstract: To satisfy people-s pursuing for individuality, an assumption of designing a new sport car was presented. Front double-wishbone suspension was designed basing on the whole vehicle-s design parameters and suspension design theories. Suspension-s virtual prototype modeling was built in ADAMS/View. By doing the design study, the assembly angles with horizontal plane of lower control arm and upper control arm were the best influential design variable on each appraisable target of suspension-s performance. These two design variable could change not only the size variation but also the trends. Cut-off point of tie rod influences toe angle greatly impacted wheels toe angle. When consider performance change and variation trend influences, optimization design was done. Lack of cornering and back to performance were ensured. The optimization results meet the demands of suspension design, and show that the suspension performance parameters achieve the ideal variation range, and is the combination of production, experiment and research.
