Abstract

The aim of this master thesis is the development and elaboration of a test methodology for the acquisition of dynamic belt deformations under as-real-as-possible and specifically defined loading conditions with subsequent construction of the test stand. The actual belt deformation profiles that can be determined in this way are used to validate dynamic belt models in simulation technology (DEM) and the belt parameters required for these models. By way of introduction, the thesis presents theoretical principles for the design and dimensioning of belt conveyors as well as methods of belt simulation in DEM and their parameter determination. An initial calculation of the relevant main data enables the subsequent conceptual design and specification of the test method as well as a variant selection for the design of the main assemblies of the belt test rig. In addition to technical, economic and operational aspects, factors such as repeatability, accuracy as well as flexibility and adaptability were also considered in the assessment. Based on the findings, the design and selection of the main system components is followed by a subsequent constructive design of the test system by creating a 3D CAD model. Details of the design, the handling of individual components of the testing system and the sequence of a belt test are described with the aid of a test protocol, and a final cost estimate of the system is carried out. The system concept is based on deforming an endless, relatively short conveyor belt by applying a large number of point loads. The point loads are arranged in a defined grid and are applied to the circulating belt with rollers. Each point load can be individually adjusted by load weights, thus characteristic bulk material loading patterns can be reproduced. In addition, depending on the application, a three-part troughing form in the upper run of the belt can be adjusted to common troughing angles. Since the local belt deformations at the respective load points correspond to the lowering of the vertically guided load linkages, the belt deformation that occurs dynamically when the belt is driven can finally be measured and a corresponding deformation profile can be generated. The test rig makes it possible to analyze the dynamic behavior of conveyor belts under conditions approximating operation with regard to belt deformation and thus contributes above all to linking virtual belt models with physical conveyor belts.
