摘　　要：研究了阻尼材料和冲压筋对平板ERP性能的影响,获得了阻尼材料和冲压筋最佳设计参数,提出了一种基于白车身大面积钣金件多工况、多目标ERP折衷规划分布云图的白车身低噪声正向概念设计流程。结合某白车身概念设计工程案例,运用该流程快速获得了车身阻尼材料和冲压筋概念设计方案,并通过ERP分析验证了该设计方案达到了NVH性能目标要求。实践表明:该成果不但可以指导概念车身钣金件振动辐射噪声性能设计,缩短详细阶段中车身NTF性能的开发周期,而且优化了概念设计阶段车身NVH性能预测评估方法,可为构建更全面的车身正向开发体系提供重要依据。In this article,firstly efforts are made to explore the effect of damping materials and stamping ribs on the plate ERP performance,in order to identify the optimal design parameters.Then,a conceptual design process is proposed for low-noise BIW based on the multi-condition and multi-objective ERP compromise programming map of BIW large-area sheet metal parts.Finally,in combination with a BIW engineering case,this process is used to quickly work out the conceptual design scheme of BIW damping materials and stamping ribs,and it is shown that this conceptual design scheme meets the requirement of NVH performance through the ERP analysis.The results not only provide guidance for the design of vibration-radiation noise performance of the conceptual vehicle body’s sheet metal parts,in order to shorten the development cycle of the vehicle body’s NTF performance in the detailed stage,but also helps to predict and evaluate the vehicle body’s NVH performance in the conceptual design stage.This study offers support for building a more comprehensive system of forward development for vehicle bodies.
