摘要
保险杠薄壁化设计具有降低零件重量、减少制造能耗、提高生产节拍等多方面优势,其所选用的改性聚丙烯材料须具备高流动、高冲击、高强度和高刚性的特点。CAE模拟明确了薄壁设计对保险杠系统模态、疲劳特性、静态下沉量及系统刚度的影响,为汽车保险杠薄壁化设计提供参考。
Thin-wall bumper design has the advantages of reducing part weight, decreasing en- ergy consumption, and improving the production efficiency of manufacturing. The modified polypropyl- ene have the characteristics of high flow, high impact, high strength and high modulus. CAE analysis indicated the influence of thin-walled design on system mode, fatigue properties, static subsidence, and stiffness performance of bumper system.
