摘要
采用“壳 -体单元相结合”的方法建立座椅计算机辅助分析 (CAE)模型 .利用Ansys软件计算了座垫弹性 ,与座椅试验的力 -变形曲线对比 ,以验证建模与材料定义的正确性 .另外还利用正面模拟碰撞中乘员的运动响应 ,分析了座椅材料的软硬程度对乘员伤害指标的影响 .
Establish the computer-aided engineering model of car seat with the methods “shell and solid elements combining”,calculate the elasticity of seat with Ansys.Compared with the “force-distortion” curve of seat test,we examine the validity of modeling and the definition of materials.The influence of seat softness to the injury index of the driver in frontal crash is also discussed.
