Abstract：Analytical solutions for basic mechanical properties of fiber-reinforced plastic plate isolators were derived. Rubber compressibility and poisson ratio were considered at the same time. And based on the pressure solution method, the equilibrium equations of a layer model under compression and bending were established to solve the solutions of pressure. The compression and bending modulus were derived by integration, and parameter analysis was conducted. And then the formula of horizontal stiffness was also achieved. A finite element model is established based on ABAQUS software to analyze the behavior of a layer model under compression and bending. The FEA results together with two analytical solutions by previous literature were compared with the solutions by this paper. Results show that the solutions by this paper have enough accuracy and obvious advantage over other solutions, which provide basis for theoretical analysis of this type of isolators uesd in rural areas.
