The computational formulations of compression stiffness and torsion stiffness of every rubber layer of laminated spherical elastomeric bearing were deduced in theory
and the theoretical results and simulated results of compression stiffness and torsion stiffness of every rubber layer of laminated spherical elastomeric bearing were compared through examples. The results show that the theoretical result of compression stiffness is basically in accord with the simulated result
the maximum error is 3.98%. There are some differences from simulated result and theoretical result for torsion stiffness in every rubber layer; the simulated result of torsion stiffness is bigger than theoretical result for the first half of all the rubber layers from the little end
the maximum error is 33.3%; the simulated result of torsion stiffness is smaller than theoretical result for the second half of all the rubber layers
the maximum error is 32.8%. The nonlinear characteristic of compression stiffness is not evident for the alterable pressure
and that of torsion stiffness is more evident with the increase of the torsion angle. But the equivalent compression stiffness and equivalent torsion stiffness got from theoretical method and finite element simulation method are in good agreement with the test results.
