一台大跨度的电动葫芦桥式起重机,在使用过程中发现端梁开裂现象。通过查阅该起重机的设计图纸等资料,利用有限元软件建模,模拟施加两种极端工况下的动载荷,分析了端梁开裂的原因。
A large-span electric hoist bridge crane, found in the use of end-beam cracking phenomenon. By referring to the design drawings of the crane and so on, the finite element software was used to simulate and simulate the dynamic load under two extreme conditions, and the reason of the end beam cracking was analyzed.
