摘　　要：对装有扭杆弹簧的独立悬架车辆车架纵梁开裂原因进行了CAE分析,并对结构进行了关联式结构改进设计,分析表明关联式结构改进设计后消除了车架纵梁开裂的状况,并在实车上得到应用,效果明显。CAE analysis on the frame carling cracking of the vehicle front independent suspension equipped with torsion bar spring, improvement of correlative structure, and analysis showed that the improved correlative structure can eliminate the frame carling cracking. It is used in practical vehicle,and the result showed it has obvious effect.
