【 摘 要 】

According to the rubber bearing, the mathematical model of rubber bearing based on geometric nonlinear is established by using Hamilton's principle. Based on the assumption of homogeneous column, the dynamics model is investigated considering the cross section rotated and the influence of the shear deformation and axial pressure. Finally, the geometric nonlinearity governing equation and boundary conditions of the rubber bearing is deduced.
