Two Degree Of Freedom

A two-degree-of-freedom nonlinear vibration system of a quarter vehicle suspension system is studied by using the feedback control method considered the fractional-order derivative damping. The nonlinear dynamic model of two-degree-of-freedom vehicle suspension system is built and linear velocity and displacement controllers are used to control the nonlinear vibration of the vehicle suspension system. A case of the 1:1 internal resonance is considered. The amplitude–frequency response is obtained with the multiscale method. The asymptotic stability conditions of the nonlinear system can be gotten by using the Routh–Hurwitz criterion and the ranges of control parameters are gained in the condition of stable solutions to the system. The simulation results show that the feedback control can effectively reduce the amplitude of primary resonance, weaken or even eliminate the nonlinear vibration characteristics of the suspension system. Fractional orders have an impact on control performance, which should be considered in the control problem. The study will provide a theoretical basis and reference for the optimal design of the vehicle suspension system.

The analysis processing for the linear coupled vibration of a flume and its inner fluid often uses FEM method. An equation set which contained the fluid node pressure and the structure node displacement is formed, based on this equation, reduction form and symmetry form is used to get the same modal frequency. Computers can calculate out the frequency more rapidly by a smaller control equation. According to the frequency comparison of different fluid-structure coupled vibration system with different materials, this paper draws some conclusions on the influence of material properties on modal characteristics for fluid-structure coupled vibration system. It can give a reference to select the material in practical engineer.
