| 摘 要： | 建立起重机吊臂结构的有限元计算模型,其中基本臂与伸缩臂在承载时的接触条件得到了仔细考虑。计算结果表明,吊臂结构具有足够的强度储备,减重设计方案使吊臂重量减小的同时,最大应力也降低了约20%。

| Abstract: | The finite element analysis model of an on-board crane winch is established,where the contact condition between the basic and removable arms is treated carefully.The results calculated from the model show that the strength condition satisfies the specifications and the mass-reduction scheme decrease both of the weight and the maximum stress by 20% at one time. |
