Asymmetrical Hysteretic Model and Parameter Identification of Disk Spring Isolator

Zeng Yi;Lou Jinjun;91592 troops Equipment Division;Naval University of Engineering Ministry of Scientific Research;  
A nonlinear hysteretic characteristic model of disk spring isolator is established.In the model,the asymmetrical hysteretic characteristics are described by the amending Y Q Ni model,and the viscous effect is expressed approximately with the viscous damping.Then parameter identification is presented according to step-by-step identification algorithm,and isolation characteristics of disc spring isolator are analyzed according to the numerical solution of the equation.Finally,the model is validated with the test data.
