Thrust rod ball hinge bionic surface improvement and finite element analysis
The bionic friction-increasing principle of locust foot pad was mainly applied to the rubber surface of the ball hinge of the thrust rod in commercial vehicles,and the bionic spherical crown-like flexible projections are constructed on the rubber ball hinge surface to increase the stiffness of the ball hinge.The height,radius and spacing of the bionic flexible projection were varied,and the radial stiffness,deflection stiffness and torsional stiffness of the thrust rod ball hinge were investigated by finite element analysis using Abaqus software.The results show that the optimum results are obtained for a projection height of 1 mm,radius of 4 mm and spacing of 10 mm.Finally,the optimal solution is analyzed comprehensively,and the feasibility of the solution is verified by simulation and experiment.
