【摘要】 基于有限元分析方法,对某车车身骨架结构进行弯曲、扭转两种工况下的模拟,得出了车身骨架结构的应力、应变分布,找出车身骨架在弯曲、扭转工况下的薄弱环节—地板前第一根横梁、第二根横梁与相应的纵梁焊接处,为车身优化设计提供了依据。更多还原

【Abstract】 The structure of an auto body frame under both bend and torsion situation is simulated with the use of finite element analysis.Then the weakness points of the auto body skeleton are found at the welding points of first crossbeam and second crossbeam with both their relative timbers,which is the reliable foundation for the optimum design of auto body.更多还原
