摘要
由于某乘用车要出口欧洲,故其座椅设计标准要满足E-NCAP,针对初始FEA分析阶段鞭打得分较低情况下对座椅头枕进行优化。在ANSA中建立座椅鞭打试验的有限元模型,利用LS-DYNA软件作为求解器,对座椅模型进行模拟仿真以提高FEA鞭打得分,根据最新数据状态进行物理试验同时与FEA结果分析对比,并根据对比结果进一步优化鞭打性能,以满足E-NCAP标准。
As a passenger car is to be exported to Europe, its seat design standard must meet E-NCAP. In the FEA analysis stage, the seat headrest is optimized for low whiplash scores. The finite element model is established in the ANSA and the LS-DYNA software is used as the solver to simulate the seat model to improve the FEA whiplash score. The object is carried out according to the latest data state in order to meet the E-NCAP standard, and the whiplash performance will be further optimized according to the comparison results.
