摘要
针对汽车滑动门保持件性能要求,建立了包含与滑动门保持件及其连接的B、C柱简化模型,选择位移载荷及力载荷进行加载,在LS-DYNA中分别对两种加载方式进行了显式的准静态分析.结果表明,力加载难以反映车门变形与施力板位移关系,位移加载能够正确反映受力与变形关系.通过滑动门保持件性能试验,验证了有限元模型,并据此提出改进设计意见.
According to the performance requirements of the retention components on a sliding door for a MPV, a simplified model is established including the door, the B-pillar and C-pillar connected with the retention components. The displacement and the force are selected respectively as the imposing load. The two kinds of loading modes are analyzed with the explicit quasi-static analytical approach in LS-DYNA. The conclusion is that the force loading is difficult to reflect the relationship between the deformation of the door and the displacement of the force application plates, but the displacement loading can correctly reflect the relationship between force and deformation. The finite element model is verified by the performance test of the retention components, and some suggestions on design are putting forward.
