Theoretical Analysis and Experimental Study of Equivalent Friction Coefficient for Hyperboloid Spherical Anti-vibration Bearing
摘要
Abstract
In order to guide the bridge and building structure seismic design and analysis, theoretical analysis, numerical simulation and experimental study are conducted to study the key parameter of equivalent friction coefficient of hyperboloid spherical anti-vibration bearing. The experimental study includes the comparative analysis of the equivalent friction coefficient with different vertical bearing capacity or loading frequency, and the equivalent stiffness and equivalent viscous damping ratio and hysteresis curve of the bearing are analyzed. The results show that the test results and the simulation results are close to the theoretical analysis results, which verifies the correctness and rationality of the theoretical formula of the equivalent friction coefficient of the bearing. Ultimately, the main basic design parameters, the test value and simulated value of the equivalent friction coefficient of the bearing are basically in agreement with the theoretical values, which further verifies the rationality of the formula.关键词
