| Abstract:Based on the basic equation of elastic mechanics under polar coordinate system, formulas of torsional stiffness for rubber dampers are derived, which would be beneficial to the design of rubber dampers and test verification. The FEA scheme of torsional stiffness, as well as the procedures are put forward, and the formulas are verified through FEA to be accurate. |
