A Variety Of Operating Condition’ Finite Element Analysis And Topology Optimization Of The Electronic Panel Saw

With the wide application of woodworking products, the research of woodworkingmachinery industry is also more and more. The electronic panel saw as important woodprocessing machinery, its main work is cutting sheet metal, the planks accuracy is processeddirectly affect the subsequent processing quality, and there is still a certain gap relative to theinternational advanced level and the current level of domestic electronic panel saw. Therefore,doing finite element analysis of electronic panel saws, improve the reliability and accuracy ofits work and make the appropriate optimization have great practical significance. In this paperthe research main idea of electronic panel saws is as follows:First of all, establishing electronic panel saws geometric model by three-dimensionalCAD modeling software Solid Edge, then I import it into HyperMesh software after thenecessary simplified, and then divide the finite element mesh, definition of material, cellproperties, contact unit and impose constraints and load.Secondly, I imported into the finite element model of ANSYS software, make staticanalysis of electronic panel saws based on three special conditions, then get the stress andstrain of the whole machine and the parts, and verify the reasonableness of its structure. Threespecial conditions:1,the electronic panel saws processing wood size is600×500×18mm，and the processing wood at one end of the workbench;2, the wood size is600×100×18mm，and locatedthe intermediate portion of the workbench;3, the wood size is600×100×18mm, during processing wood board is located in the middle of the workbench and sawnthe remaining material for10mm.Then, using ANSYS software to make modal analysis of the electronic panel saw and getits first twelve-order natural frequency and main vibration mode, and analysis the each ordermain modes. According to these natural frequencies, it can provide based data for avoidingresonance phenomena in the work process of electronic panel saw.Finally, based on the artificial material density topology optimization theory andtopology optimization criterion about variable density method, I use the OptiStruct module ofthe finite element analysis software HyperWorks to make topology optimization for thepressure beam and compare its static characteristics before and after optimization, under thepremise of a high reliability, to achieve a reduction in weight of the pressure beam structure,thus effectively reducing the production cost.By finite element analysis, we can conclude that the electronic panel saw structure is reasonable, reliability of cutting and sawing work properly is very high, the quality of theprocessed products can meet the accuracy requirements, and it also laid the foundation toimprove its structure.
