摘　　要：从理论上推导了叠层球面橡胶-金属弹性轴承各胶层的压缩刚度和扭转刚度计算公式,探讨了胶层压缩刚度、扭转刚度的等刚度设计方法,并将等压缩刚度和等扭转刚度设计方案的理论计算结果、有限元仿真结果分别与未进行等刚度设计方案的结果分别进行了计算和对比,结果表明,等刚度设计可以很大程度上消除不同胶层之间的刚度差异,各胶层压缩刚度和扭转刚度的理论计算结果与仿真结果基本吻合。The formulations of compression rigidity and torsion rigidity of laminated spherical rubber-metal elastomeric bearing were de-duced 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.
