Research on Simulation Modeling of the Compression-shear Testing Machine Structure and the Centralized Pump Station Hydraulic System
In order to improve the overall stability and reliability of the compression-shear testing machine,research was conducted on the simulation modeling method of the structure of the compression-shear testing machine and the hydraulic system of the centralized pump station.Analyze the structure of the compression-shear testing machine,clarify the working principle of the structure,determine the detailed process of controlling the structure of the compression-shear testing machine by the hydraulic system of the centralized pump station,use Abaqus finite element software dedicated to mechanical structure to construct the finite element model of the compression-shear testing machine structure,and simulate and analyze the effect of the hydraulic system of the centralized pump station on the finite element model of the compression-shear testing machine structure in MATLAB simulation testing software,analyze the changes in the compression-shear testing machine through simulation models.The simulation results show that using the centralized pump station hydraulic system to act on the finite element model of the compression-shear testing machine structure can significantly improve the displacement changes of the compression-shear testing machine,avoid deformation of the compression-shear testing machine,and enhance the stability of the testing machine.Simultaneously using the centralized pump station hydraulic system can reduce the strain value of the testing machine,and the control accuracy is always above 90％,which can improve the reliability of the testing machine.
