【摘要】：近年来，随着中国社会的发展和工程建设规模的扩大，起重安装工程量越来越大，对起重机的需求越来越大，汽车起重机已经成为各厂家主要发展对象。本文以QY50P汽车起重机吊臂系统为研究对象。通过对吊臂系统的力学分析，建立吊臂系统的基本力学模型，并利用ANSYS软件，建立吊臂系统有限元分析模型并进行有限元分析。初步掌握吊臂系统力学模型及有限元分析模型的建立方法、简化原则，并通过分析获得吊臂系统的受力状况、危险截面位置及对吊臂系统受力情况会产生不利影响的结构形式。根据所得结果对吊臂系统设计提出合理性建议。在此基础上以通用有限元分析软件为平台引入了参数化思想，运用ANSYS自带的参数化设计语言APDL完成对ANSYS的二次开发，实现吊臂系统有限元分析的参数化。为降低分析过程中的工作量并提高分析效率，通过Visual Basic软件对参数化的吊臂系统分析程序进行封装和界面化，实现了对有限元分析软件ANSYS的调用与封装，，从而形成参数化、专业化的吊臂系统有限元计算程序。该程序封装了所有ANSYS的操作，用户只需要进行设计变量的输入，吊臂分析模型创建、有限元参数化分析流程文件、调用ANSYS计算都由程序自动完成，并能对起重机载荷表进行自动计算和输出。
[Abstract]:In recent years, with the development of Chinese society and the expansion of engineering construction, the amount of lifting and installation works is increasing, and the demand for cranes is increasing. Truck cranes have become the main object of development of various manufacturers. In this paper, the jib system of QY50P truck crane is taken as the research object. Through the mechanical analysis of the jib system, the basic mechanical model of the boom system is established, and the ANSYS software is used. The finite element analysis model of the boom system is established and the finite element analysis is carried out. The method of establishing the mechanical model and the finite element analysis model of the boom system is preliminarily grasped, the simplified principle is obtained, and the stress condition of the boom system is obtained through the analysis. The dangerous section position and the structure form which will have a negative effect on the stress condition of the boom system. According to the results obtained, the reasonable suggestions for the design of the boom system are put forward. On this basis, the idea of parameterization is introduced on the platform of general finite element analysis software, and the secondary development of ANSYS is completed by using APDL, the parametric design language of ANSYS. In order to reduce the workload and improve the efficiency of the analysis, the finite element analysis of the boom system is parameterized. The parameterized system analysis program is encapsulated and interfaced by Visual Basic software, and the finite element analysis software ANSYS is called and encapsulated to form parameterization. Specialized finite element program for boom system. The program encapsulates all the operations of ANSYS. Users only need to input the design variables, create the analysis model of the boom, and parameterize the flow file of finite element analysis. The ANSYS calculation is done automatically by the program, and the load table of crane can be calculated and output automatically.
