推导了具有柔性增强件的无限条形叠层弹性轴承压缩刚度的闭式解。考虑了弹性层体积压缩性的影响和轴承端部边界条件的影响。研究了三种类型的与柔性增强材料粘合的弹性层。第一种类型模拟具有无剪切端的轴承的内部弹性层。第二种类型模拟自由端轴承的外部弹性层。第三种类型模拟轴承中的弹性层，其端部粘合到刚性板。轴承压缩刚度的理论解与有限元法得到的结果极为接近，证明理论推导中采用的位移假设是合理的。
The closed-form solutions to the compression stiffness of the laminated elastomeric bearings of infinite-strip shape with flexible reinforcements are derived. The effect of bulk compressibility in the elastic layer and the effect of boundary condition at the ends of the bearing are considered. Three types of the elastic layers bonded to flexible reinforcements are studied. The first type simulates the interior elastic layers of the bearings with shear-free ends. The second type simulates the exterior elastic layers of the free-end bearings. The third type simulates the elastic layers in the bearings which ends are bonded to rigid plates. The theoretical solutions to the compression stiffness of the bearings are extremely close to the results obtained by the finite element method, which proves that the displacement assumptions utilized in the theoretical derivation are reasonable.
