Research On Optimization Design For The Crossbeam Component Of Ceramic Tile Edge Grinding Machine Based On Finite Element Analysis

The edger is an important part of the deep processing of porcelain bricks,which directly affects the production precision and product quality of porcelain tiles.The beam component is a key mechanism for carrying the grinding wheel,the pressure beam and the arm mechanism,which is directly related to the grinding.The key to improving the beam performance of the edge machine is to improve its static and dynamic characteristics.This paper first introduces the structure and production process of the dry grinding and edging machine.By comparing the magnitude of the overturning moment under different sizes,the size of the porcelain brick in the maximum working condition is determined.Based on the difference of grinding wheel grinding force,the mechanical model under the condition of beam component is established.According to the principle of force translation,the load conditions of the beam assembly under grinding and adjusting conditions are obtained.Secondly,by the meshing,adding constraints,and applying loads in the ANSYS finite element analysis software,the static and dynamic characteristics of the beam component are analyzed,and the static and dynamic characteristic cloud images are obtained,which is the key to the next step.The basis for dimensional sensitivity analysis and structural optimization schemes has been laid.Thirdly,taking the key dimension of the beam component as the design variable,taking the maximum deformation under the working condition as the objective function,taking the maximum stress value,the total mass,the first-order natural frequency as the constraint,and using the DOE module to analyze the sensitivity of the design variable..Based on this,the ANSYS software is used to calculate multiple design points under the objective function and constraints.The MOGA algorithm is used to screen out the optimal design points,and the static and dynamic characteristics are analyzed.Then,based on the original structure,two schemes of adding support members at the middle end of the beam and inverting the main frame of the beam are designed,and the model is re-modeled by using 3D software.By comparing the static and dynamic characteristics of the two structural optimization schemes with the original structure,namely the maximum shape variable,the maximum stress value,the total mass and the first six natural frequencies,the two optimization schemes are analyzed.Finally,the strain component is subjected to strain testing using a resistive stress-strain test system.By testing the random three-point strain value on the beam structure,the recording is performed and compared with the simulation results.
