Bench calibration of load spectrum measurement for fighter airplane main undercarriage;

Chinese aircraft engineers are now much interested in understanding better the longitudinal nonlinear buffet of main landing gear (also called gear walking) during aircraft taxiing And braking on the runway.

Optimal placement of semi-active control devices in controlled structure;

Study on semi-active control of highway bridge pounding under seismic excitations;

Research on semi-active control of ocean vehicle multi-dimension vibration;

First,a detailed review of semiactive control systems is provided including the recent advances in design of both control devices and control algorithm.

Authors introduced a new semiactive control system,active variable stiffness·damping(AVS·D) system,whose composition and work principle were described.

As one of classical examples of semiactive control system, variable dampers are widely used for structural control.

In this paper, four semi active control algorithms are presented.

A Fuzzy semi active control suspension system in which the MR dampers are used to replace the passive dampers as the semi active control actuators has been proposed and developed based on the analytical and experimental investigations of the MR fluid and the MR damper.

when the eleetro rheological damper is provided with semi active control system,its damping and stiffness at working condition can be adjueted timely,which makes the wibrational effects get increased greatly.
