臂架式起重机起重特性计算

Calculating the Lifting Capability of the Jib Crane

利用SAP2000开放的应用程序接口对其进行二次开发,结合Excel VBA编程实现对臂架式起重机起重特性的自动计算,将计算结果输出到Excel数据表中直接生成起重特性表,并绘制起重性能曲线,从而实现了利用有限元软件对起重特性表计算的程序化和自动化,提高了工作的效率和起重特性表的准确性,最后对载荷迭代算法进行了研究,提出一个适用于多种工况计算的高效算法,并通过计算实例表明该计算方法是切实可行的。

Carrying on a secondary development of SAP2000 with its open application programming interface,automatically computing the lifting capability of jib crane and combining with Excel VBA programmin is realized.The results will be outputted to Excel data table and also generated the lifting capability table and lifting capability curve directly.Therefore the lifting capability can be computed with Finite Element Software programmatically and automatically.Both the accuracy of lifting capability table and the work efficiency are improved.Finally,the iterative algorithm for loads is studied and an efficient algorithm is proposed for computing the various working conditions,and then a computing example shows that this calculation method is practical.
