Nonlinear and Nonstationary Random Vibration of Hysteretic Systems with Application to Vehicle Dynamics
The nonstationary response of a nonlinear multi-degree of freedom vehicle model is obtained. The suspension is of hysteretic nonlinear type and nonstationarity is due to variable velocity traverse. The road excitation is modelled as the response of a time variant filter to modulated white noise. Equivalent linearization method is adopted and response statistics are obtained by numerical integration of matrix differential equations.
