瞬态冲击响应的数值技术及其在120t平车设计中的应用

Numerical Technique of Transient Impact Response and Its Application in 120T Flat Wagon

１２０ｔ钢锭运输平车经常承受突然的冲击载荷．在讨论了基于振型迭加法的瞬态冲击响应的关键技术之后，用 Ｉ－ ＤＥＡＳ软件对 １２０ ｔ平车钢结构进行了瞬态冲击响应计算，其计算结果对设计十分重要．

Based on the modal superposition technique, 120t flat wagon subjected to impact load is studied and several techniques are given. The numerical results of 120t flat wagon caculated by I-deas software are most helpful for structure design.
