The Principle of Equivalent Center of Mass of FPB & Superstructure
2012
Elaborates on the differences between FPB structure in practical uses and classical models, and puts forward a principle of equivalent center of mass of FPB & superstructure by dynamic analysis. It conducts FEA and experimental validation based on the post yield stiffness and vertical displacement calculated in accordance with the principle. The conclusion states that calculating the post yield stiffness and vertical displacement of the bearing by the principle is more accurate than before.
