Equivalent Rigidity Design Research of Laminated Spherical Rubber-metal Elastomeric Bearing

  The formulations of compression rigidity and torsion rigidity of laminated spherical rubber-metal elastomeric bearing were deduced by theoretical means, the designed means of equivalent compression rigidity and equivalent torsion rigidity were studied, for the equivalent rigidity plan and unequal rigidity plan, the theoretical results and finite element simulated results of compression rigidity and torsion rigidity are calculated and taken comparied respectively, the results show that the equivalent rigidity design can eliminate the rigidity difference between different rubber layer to a large extent, the theoretical calculated results of compression rigidity and torsion rigidity are basically identical with the simulated results in every rubber layer.
