Anslysis Of The Influence About The Fray Of Wire Rope Due To Multilayer Winding Drum And Guide Plate

Along with our country's economy pattern adjust and change,port service, ocean engineering is becoming the key areas in China. Large hoisting machinery is an important equipment in port which used by cargo handling and Marine engineering, with the lifting of tonnage and service range of demand is higher and higher,large tonnage, high-lift crane has become an important equipment in modern port that loading and unloading. Research a small size and big volume multilayer winding system is a hot issue.The key is the structure of the multilayer coiling wire rope drum.Guide plate is the important part of the drum,it has important influence on the crosswinding functions of the wire rope. Based on the wear test of the multilayer coiling wire rope-pulley,whicn is developed by WHUT and Japan, the influence relation between shape of guide plate and service life of wire rope is researched particularly.In this paper, the research object are the drum and guide plate used in the project. The force condition of the multilayer coiling wire rope drum is simulated by the Finite Element Analysis Software ADAMS, and the force on the wire rope is also simulated under the condition of different guide plate, this can provide evidence for the reasonable selection of the size of the reasonable selection.This thesis main jobs:(1) Introduce several different types of drums, deduce the wire rope around the tension on the drum calculation formula. Introduce wire rope-pulley wear test, and analysis the influence of fray of the wire rope by the guide plate.(2) According to the actual size, use software build the model of the drum, and make wire rope rolling around on the model,introduce the guide plate's function when the wire rope change layer,make us kown how the wire rope contact with the guide plate, lay the foundation for the analysis of force on the wire rope.(3) Summary wire rope-pulley test about the guide plate in the test data, use ADAMS analysis the problem of the contact between guide plate and wire rope, and compare the platform data with the results, according to the guide plate's modified, the model make corresponding adjustment, and then proceed the simulation analysis,the improve of wire rope's service life obtain simulation technology support. To improve the service life of the wire rope, and put forward some personal opinions in the direction of guide plate.
