This paper makes an analysis to the stable response of helical spring mass system under impact load.

A comparative analysis for stable response of dry soils and saturated soils is performed.

The dynamic properties of the transmission wire of contact net were analysed and the stable response of the transmission wire was obtained by the modal analysis.

Calculation of the steady state response of locally nonlinear dynamic systems by harmonic balance method;

The steady state response to angle input of multi-steering wheels was analyzed.

Semi-active control for steady state response of a non-linear isolation system with a non-linear dynamic vibration absorber is studied in the paper.

Numerical analysis and experiment of counter-rotating dual-rotor s steady-state response;

The steady-state response of a vehicle is often evaluated by the steady-state yaw velocity and front wheel angle at a equal speed.

The three-series solution is taken up to the nonlinear differential equation of the galloping movement caused by the cross wind force acting on a high-rise structure, thus giving a reduced 3D expression in terms of steady-state response and critical wind speed.

After finding the orthogonal sets corresponding to the guided-wave restriction condition,the analytic dispersive equation,group velocity equation and steady response are obtained simultaneously.

In order to understand the differences of amplitude and critical speed between steady response and transient response,and to find the acceleration how to impact the transient response of rotor,we contrast them at the Jeffcott rotor,cantilever rotor with one disc and double-disc rotor.
