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。
Use SAP2000 open application program interface to carry on secondary development to it, combine Excel VBA programming to realize the automatic calculation to the boom-type crane lifting characteristic, output the calculation result to the Excel data table to generate the lifting characteristic table directly, and draw up Heavy performance curve, so as to realize the program and automation of the calculation of the lifting characteristic table by the finite element software, and improve the working efficiency and the accuracy of the lifting characteristic table. At last, the load iteration algorithm is studied, A variety of operating conditions efficient calculation algorithm, and through the calculation example shows that the calculation method is feasible.
