Parameter Identification of Quasi-static Asymmetric Hysteresis Model for Wire-rope Isolators
摘要
Abstract
The wire-rope isolator has obvious nonlinear hysteretic characteristics because of the dry friction among the wires. In the literatures, most of the parameter identification of hysteresis model was based on the initial deformation-free assumption. In fact, there must exist some initial deformations in the wire-rope isolator since it is loaded. Due to the strong nonlinearity of the wire-rope isolator, its hysteresis parameters depend on initial deformations. In this paper, according to the experimental hysteresis curve of the isolator with rated load, and considering the high-order stiffness and the varying damping, a quasi-static asymmetrical hysteresis model was presented through the parameter identification. The results show that the hysteresis of the theoretical model is in consistent with that from the experiment. Therefore, the model can well reflect the quasi-static non-linear stiffness and damping characteristics of wire-rope isolators.关键词
