Optimization Of Sub-beam Structure Of Sand Mixing Vehicle Based On Finite Element Analysis

With the development of industrial technology,the status of petroleum in the international market is increasing.Fracturing technology as a high-efficiency mining technology has become the key to increasing oil production.As a key part of fracturing operations,sand mixing vehicles have mixed and stirred sand medium.The function is complicated,the working environment is harsh,and the structural quality of the whole vehicle is required.As the main bearing mechanism of the sand mixing vehicle,the auxiliary beam is the key link for the normal operation of the sand mixing vehicle.The sand mixer has a variety of components,including the engine,operating platform,mixing tank and auger.The components are compact.In the engineering application,the bending condition of the sub-beam of the sand mixing vehicle often occurs,which affects the working efficiency of the sand mixing vehicle and has certain safety hazards.Based on the original sub-beam,this paper has optimized the material and structure.Simplify the main and auxiliary beam structure,set the quality point of the top-loading component,create the ANSYS finite element model,and perform equivalent processing on the unsprung part to determine the boundary conditions.The workbench function is used to perform static analysis on the main and auxiliary beams before and after optimization,and the analysis results are processed and evaluated.The free mode and the constrained mode of the auxiliary beam structure before and after optimization are analyzed,and the excitation frequency of the engine and the road surface are determined.The sub-beam resonance deformation is evaluated by the natural mode vibration mode of the auxiliary beam.The harmonic response analysis of the auxiliary beam is carried out,the engine frequency excitation load is input,the deformation frequency curve of the engine installation position is output,the result is processed by data,and the response curve of the auxiliary beam at the position before and after optimization is evaluated.
