摘　　要：汽车起重机伸缩臂是重要的承载部件,同时也决定了整车的起重能力。由于伸缩臂存在多种伸缩组合方式,其有限元计算模型随着伸缩组合发生变化,增加了伸缩臂分析的难度。通过采用数据处理软件Matlab作为前处理工具,输出包含伸缩臂的结构尺寸参数、各伸缩组合下臂节的位置参数的文本文件。同时,基于Ansys参数化设计语言APDL,建立伸缩臂的参数化有限元模型及分析流程。通过读取文本文件数据,实现臂架强度的快速计算,使用比例迭代法计算在指定工况下的额定起重量。通过使用APDL与Matlab的联合仿真,在保证计算精度的同时大幅提升了有限元分析效率。The telescopic boom of a truck crane is an important load-bearing component,which also determines the overall lifting capacity.Due to the existence of multiple telescopic combinations,the finite element calculation model of the telescopic boom changes with the telescopic combination,which makes the telescopic boom analysis harder.By using the data processing software Matlab as a pre-processing tool,a text file containing the structural dimensional parameters of the telescopic boom and the positional parameters of the boom joints in each telescopic combination is output.At the same time,based on Ansys parametric design language(APDL),a parametric finite element model and analysis process of the telescopic boom are established.By reading the text file data,rapid calculation of the boom strength is achieved,and the rated lifting capacity under specified working conditions is calculated using the proportional iterative method.By using the joint simulation of APDL and Matlab,the efficiency of finite element analysis is greatly improved while ensuring the calculation accuracy.
