| Summary: | 碩士 === 國立臺灣科技大學 === 營建工程系 === 93 === The reinforcing elements of laminated rubber bearings, which are normally steel plates, can be replaced by the fiber reinforcement. The fiber-reinforced isolator is significantly lighter and could lead to a much less labor-intensive manufacturing process. So the fiber-reinforced isolator will become the trend in the future.
In this research the finite element method is applied to analyze the circular fiber-reinforced isolators for different shape factor and compressibility of elastic layers. The analyzed results under variant parameters are compared to observe the influence on the compressing and tilting of isolators.
The results of finite element analysis show that the effective compressive stiffness and the effective bending stiffness increases with increasing of Poisson’s ratio and shape factor of elastic layers, and decreases with the increasing the stiffness ratio of elastomer to fiber or numbers of elastomer layers. In a situation that shape factor is larger and elastic layer’s Poisson’s ratio is larger, the assumption that the horizontal plane remains plane after deformed used in theoretical derivation is not completely consistent with the result of the finite element analysis, but there are some similarity in certain degree.
