Finite element analysis of steel cord conveyor belt splice

Steel cord conveyor belt splices are connected by vulcanization. The splices are the weakest part of the conveyor. Taking type ST1250 conveyor belt splice as an example, finite element software ANSYS is used to establish the necessary model, dealing with the steel cord as elastic components and the rubber as hyper-elastic Mooney-Rivlin model. The APDL language in AYSYS is used to develop a calculation program. After analysis, the conclusion was drawn that the conveyor´s vertical tension must be transferred through the shearing stress between the rubber in the splices zoom and wire rope, and the distances between the wire rope must be wide enough to ameliorate the stress condition of rubber. For the high-strength belts, due to the high density, only by increasing steps can meet this requirement.
