| In this paper, there had been Carried on dynamics analysis to the EBZ-160-typeboring machine’s caterpillar band Caterpillar band walking install.Firstly, introduced theEBZ-160-type boring machine characteristics and crawler works. On this basis,the papersuffered on the crawler loads analysis and establish to Mechanical model. Comiingcrawler traction and driving resistance of the theoretical formula. Then,through threedimensional modeling software PRO/E can get its three-dimensional modeling,gettingsimplified three-dimensional model crawler. Using a multi-body system dynamics asthe theoretical basis, let the three-dimensional modelwhich made of PROE building intomulti-body dynamic analysis software ADAMS. In dynamic analysis software ADAMSadd the constraint, applied load and so on.For the boring machine under the two conditions on level ground and climbing,the output power for constant torque and constant speed in both cases, the crawler forthe dynamic analysis, focused on the driving wheel and the track plate meshing forceanalysis. Extraction and Analysis of the driving wheel and the meshing force as thelargest wheel and crawler load finite element analysis of plate boundary conditions. InANSYS for the strength check of the driving wheel and fatigue analysis, there are on thetrack and contact with the ground for analysis and fatigue analysis, validation wheel andtrack meet strength requirements of the board.By study of EBZ-160Roadheader crawler kinetics for the boring machine,whichprovide a technical basis for designing boring machine, at the same time for other largecrawler device dynamics simulation provides a method and for the product developmentprocess prototype manufacturing costs, shorten development cycles, have practicalsignificance. |
