Research on middle beam pin shaft node of hydraulic support test bench based on AHP-Fuzzy analysis model
In order to improve the situation of discontinuity in the range of stresses caused by pin deformation, the mathematical theoretical model of peak contact stresses after pin node deformation in the test rig was established based on the Hertzian contact theory, and the pin node model was simulated and...
