Belt Conveyor Truss Beam Finite Element Analysis And Visualization

Truss, as a main structure form in metal structure, is widely used inhoisting and conveying machinery, construction, bridge, factory plant and othersupport skeletons, with the characters of light weight, high rigidity, goodanti-seismic performance, saving in materials, etc.. This paper introduces a pipebelt conveyor truss beam structure as an example, the truss beam structure ofthe finite element analysis. In the visualization process, dividing mechanicsanalysis into two big modules as the target system: conventional calculation andfinite element analysis.Conventional calculation module: According to the physical model of thetruss beam, set up a corresponding mechanics model. Analyze various forms ofloads that the truss beam bears, determine the conditions and select loadcombination, conclude the recursion formula of truss beam internal forcecalculation to calculate the internal force of each truss beam member and checkthe strength, rigidity and stability of rod pieces, and at last set the designcalculation specification.Finite element analysis module: Establish the finite element model of trussbeam, use software ANSYS to process finite element analysis, and compileAPDL programs to complete three steps of the parametric analysis of finiteelement：pre-treatment, solution and post-treatment. And output the stress andstrain cloud.This article first made the overall demand analysis of the target system, andthen the corresponding functional analysis was conducted on the basis of thedemand analysis. According to the mechanical analysis process of truss beam,workout corresponding program with Visual C++language. With theestablishment of friendly human-machine interface, process parameter design,realize data sharing, and improve the visualization degree of the system.Calculation result analyzed would be outputted in the form of text to generatethe design specification, making accurate data available to users, which greatlyreduced the design personnel’s workload. Finally combined with engineering projects, the two big modules were conducted respectively with proceduresdesigned in this article, the conventional calculation and finite element analysis.Generate the calculation specification, and contrast the result of theconventional calculation with that of the finite element analysis, finding that thecalculation results were close and both of then met the engineering requirements,which reflects the superiority of finite element analysis visual software of trussbeam based on APDL, and has certain engineering practical value.
