【摘要】：随着我国经济格局的调整和转变,港口服务、海洋工程正成为我国经济发展的重点领域。大型起重机械是港口货物装卸和海洋工程的重要装备,随着起升吨位和服务范围的要求越来越高,大吨位、高扬程的起重机已经成为现代港口装卸和海洋工程服务的关键设备。研究具有较小尺寸的大容绳的多层卷绕系统是目前大型起重机的热点问题。其中多层卷绕卷筒的构造是实现高质量多层卷绕的关键。导向垫块是多层卷绕卷筒上的重要部件,其对卷筒钢丝绳的卷绕性能具有重要的影响。本文以武汉理工大学与日本合作研究项目——多层卷绕钢丝绳—滑轮磨损试验研究为依据,以项目试验中的卷筒及垫块作为研究对象。运用有限元分析软件ADAMS来模拟多层缠绕钢丝绳卷筒工作时的受力,以及模拟不同导向垫块作用下的钢丝绳受力,对导向垫块的形状与钢丝绳的使用寿命之间的影响关系进行了细致的研究,为多层卷绕钢丝绳卷筒设计中导向垫块尺寸的合理选择提供依据。本文所做的主要工作有： (1)介绍了几种不同卷筒及其强度计算方法,推导了钢丝绳缠绕在卷筒上时的张力计算公式。通过钢丝绳—滑轮磨损试验装置,分析了导向垫块对钢丝绳的磨损影响。 (2)构建了卷筒的3维模型和钢丝绳在卷筒上缠绕模型,分析了导向垫块在钢丝绳换层过程中起的作用,得出了钢丝绳与导向垫块的接触轨迹,为钢丝绳的受力分析打下基础。 (3)利用ADAMS软件分析导向垫块与钢丝绳接触的问题,并与钢丝绳—滑轮试验所得的结果相比较,按照试验中对导向垫块的修改,在模型中做出相应的调整,再进行仿真分析,得出了钢丝绳寿命延长在仿真技术上的支持。对导向垫块与提高钢丝绳工作寿命的关联问题,提出了几点个人意见。
[Abstract]:With the adjustment and transformation of China's economic structure and port service, marine engineering is becoming a key area of economic development in China. Large lifting machinery is an important equipment for port cargo handling and marine engineering. As the requirements for lifting tonnage and service range become higher and higher, large tonnage, The high lift crane has become the key equipment of the modern port loading and unloading and ocean engineering service. The research on the multilayer winding system with small size large capacity rope is the hot issue of the large crane at present. The construction of tube is the key to realize high quality multilayer winding. The guide pad is an important component on the multi-layer winding drum. It has an important influence on the winding performance of reel wire rope. This paper bases on the research project of Wuhan University of Technology and Japan on the wear test of multi-layer winding wire rope and pulley. Taking the reel and gasket in the project test as the research object, the finite element analysis software ADAMS is used to simulate the force acting on the multi-layer winding wire rope reel, and to simulate the force of the wire rope under the action of different guiding blocks. The relationship between the shape of the guide pad and the service life of the wire rope is studied in detail, which provides a basis for the reasonable selection of the size of the guide pad in the design of the multi-layer winding wire rope reel. The main work of this paper is as follows:. This paper introduces several kinds of different reels and their strength calculation methods, deduces the formula of tension calculation when the wire rope is winding on the reel, and analyzes the influence of the guide pad on the wear of the steel wire rope by means of the wire rope pulley wear test device. 2) the 3D model of reel and the winding model of wire rope on the reel are constructed. The function of the guide pad in the process of changing the layer of the wire rope is analyzed, and the contact track between the wire rope and the guide pad is obtained, which lays a foundation for the force analysis of the wire rope. 3) using ADAMS software to analyze the contact problem between guide pad and wire rope, and compare with the result of wire rope pulley test, according to the modification of guide pad in test, make corresponding adjustment in the model, and then carry on simulation analysis. The support of the simulation technology for prolonging the life of steel wire rope is obtained. Some personal opinions are put forward on the connection between the guide pad and the improvement of the working life of the wire rope.
