【摘要】 按欧洲法规ECE R29正面摆锤撞击试验对某商用车进行出口认证,出现驾驶室前悬置支架断裂、转向机构向上和向后移动、驾驶室严重压溃变形等问题,进行了CAE优化设计和结构研究分析,采取合理有效的改进措施,使得最终优化方案通过了实车验证试验。介绍了现行ECE R29-02的修订案ECE R29-03,后者加大了正面撞击能量,对驾驶室强度和刚度提出了更严格的要求,为我国商用车新产品研发和出口提供了最佳设计指导和国际法规引领作用。更多还原

【Abstract】 In the export approval of a commercial vehicle cab according to ECE R29 front impact,some problems were found,such as cab front suspension brackets were broken;steering column and wheel was removed upward and rearward;cab was deformed seriously and so on.In order to improve these unreasonable design constructions,CAE analysis and construction improvement concerning these parts were completed.Meanwhile,reasonable and effective design measures were taken.Eventually,the improved design passed the test.The revised ECE R29-03,which increased the front impact energy,requires stricter on cab strength and rigidity than ECE R29-02.Optimum design and international regulation guide were provided for Chinese commercial vehicle R&D and export.更多还原
