Modal Optimization of Body-in-White Based on Modal Strain Energy and Sensitivity Analysis

  • 摘要: 白车身优化过程中,由于板件较多,直接使用模态灵敏度分析的分析对象多且计算量大。本文引入模态应变能分析方法,从而减少模态灵敏度分析对象,提高优化效率。基于模态试验验证的有限元模型,选取模态应变能分析的一阶模态振型下的薄弱位置,缩小模态灵敏度分析的板件范围,再根据灵敏度分析结果对板件厚度进行调整,提高白车身一阶模态频率。最终结果表明,优化后一阶模态频率由15.75 Hz提高到了16.50 Hz,同时白车身质量未增加,实现了白车身模态性能提升的同时车身不增重。
