摘要
为缩短轿车转向盘开发周期,减少试验损耗,建立了轿车转向盘骨架有限元模型,并对转向盘骨架进行了模态分析、静强度分析,分析结果显示所建立的模型满足设计要求与静强度要求。之后进行了动态冲击分析,模型经过跌落冲击试验验证后,依据ECE R12法规进行数值分析,结果表明,转向盘的动态冲击分析与试验具有良好的一致性。文中模拟分析方法适合于转向盘的前期开发阶段,能为转向盘改进提供理论依据,可有效降低试验费用和开发周期。
In order to shorten the development cycle of the steering wheel of vehicle and reduce the test loss, finite element model of steering wheel frame is established, modal and static strength analyses are proceeded. The simulation results show the model can meet both the design requirements and the static strength requirements. Dynamic impact analyses are proceeded and numeri cal analysis is done according to ECE regulation RI2 after being validated by drop test. The simulation results show the uniformity between impact analysis and the test. The analytical methods are suited to development stage of steering wheel, and may provide the oretical grounds, reduce test costs and development cycle.
