摘　　要：针对大吨位汽车起重机的起重性能计算问题,在ANSYS平台上进行二次开发,得到了汽车起重机起重性能计算软件。首先,将大吨位起重机臂架及整机结构特征进行参数化;其次,进行臂架有限元参数化建模,调用ANSYS求解器,进行静力学计算;最后,利用综合安全评判体系对计算结果进行判定,迭代计算获得起重性能计算结果。软件界面开发模块采用TCL/TK语言,其他模块采用APDL语言。在汽车起重机产品上进行了吊载试验,试验结果表明:软件计算值和试验值吻合较好。起重性能计算软件计算效率高,涵盖了汽车起重机所有作业工况的起重性能计算。In terms of the calculation problem for lifting capacity of mobile crane, the lifting capacity calculation software for mobile crane is developed on the ANSYS platform based on related theory algorithms. Firstly, the structure characteristics for crane boom and the whole machine are parameterized. Secondly, the finite element parametric model of crane boom is established. The nonlinear static analysis is executed by calling ANSYS solver. Finally, the calculation results are appraised by virtue of safety evaluation system. Lifting capacity results are obtained through iterative calculation. Software interface module uses the TCL/TK language and the other modules use the APDL language. The crane load test in mobile crane is carried out. Experimental results show that there is a good agreement between calculation value and experimental value. The developed software has high computational efficiency and covers all mobile crane＇ s operating cases.
