摘　　要：汽车悬架性能对操纵稳定性与行驶平顺性具有重要影响。文章以紧凑型轿车奔腾B30为目标车型,根据其车型参数、用户需求,匹配相适应的前悬架类型为麦弗逊式。对麦弗逊式悬架关键零部件包括弹簧、减振器、横向稳定杆进行结构设计和强度校核。基于以上设计计算结果,利用ADAMS/Car构建了简化的悬架模型,给予车轮同向激励,获得前轮定位参数变化范围,通过修改硬点位置获得合理的前轮前束角的变化范围,改善了汽车操纵稳定性。Automotive suspension performance has a major impact on handling stability and ride comfort.This paper takes the compact car Pentium B30 as the target model.According to its vehicle parameters and user requirements,the matching front suspension type is McPherson.The structural design and strength check of the key parts including springs,dampers,and stabilizer bars is carried out.Based on the above design calculation results,a simplified suspension model is constructed by ADAMS/Car,the wheel is given the same direction excitation,the range of front wheel positioning parameters is obtained,and the range of the front wheel toe angle is improved by modifying the hard point position.At last,the steering stability is improved.
