Research And Application Of POT Rubber Bearing

The bearing of bridge is an important component which is used to connect structures. The superstructure of bearing's reaction and distortion (displacement and corner) can be delivered to the lower part of the structure by bearing. Its mechanical properties and reliability have an important effect on the normal load and security of bridge. This article is focus on the mechanical properties and Structural parameters of Pot rubber bearing that has much implication on the bridge by FEA. Several problems are solved as follows:1. Rubber materials features and FEA: Poisson's ratio of rubber is obtained by comparing the result of FEA and experiments. Some valuable results is obtained through computing and analyzing rubber under triple-dimensional stress.2. Non-linear finite element, non-linear geometry and contact FE are introduced to bearing calculation, which describes the structure model of bearing more explicitly. The calculative model of Pot Rubber Bearing is obtained by compared the computing results and experimental results of Pot Rubber Bearing.3. Main design parameter was introduced such as rubber thickness, link thickness, bottom thickness.Several parameter span of Pot Rubber Bearing is introduced in this article and that provide the refer prejudice for the design of bearing.4. The re-development is based on the object-oriented programming language VC and ANSYS APDL language. What's more, the programming make bearing analysis as well as calculation more easier and convenient, eliminating redundant modeling and analysis malpractice, and reducing the massive operating time.So this article's research has provided certain auxiliary and the reference function for support's design and application.
