摘要
将主梁看作线弹性结构,利用莫尔定理推导了满载小车在跨中和悬臂端时主梁下挠度的解析表达式,并进行了实例计算;最后引入了建筑结构设计程序PKPM对主梁的下挠度进行了仿真,仿真结果与解析法计算结果相似,证明了2种方法在起重机设计中的可行性。
The girder is regarded as a flexibility structure, then the solution was carried out based on the Mohr＇s theorem. Besides, the PKPM, a program which is used for design of an architecture structure, was introduced to conduct a simulation for an practical example on crane design. Results proved that the two methods mentioned above have some practical significance.
