龙门起重机空间整体结构计算模型探讨

Probing and discussion about the calculating model of the spatial structurs of gantry cranes

空间结构计算模型比通常所用的平面计算模型更逼近实际.用空间整体计算模型能更清晰地分析各构件的受力状况,设计出的电动葫芦龙门起重机与实测结果对比后表明,它更符合于实际工作状态.该计算模型也能用于其它类型的起重机设计.

A spatial calculation model of spatial structures is more precise than a simplified plane one. The spatial model can be used to clearly analyse the forces in various components, Its results conform well to the date tested from a real gantry crane designed with it.It can also be used to design other types of cranes.
