Abstract: The technical status and the lastest research progress of active suspension structure technology for military vehicles are introduced, and the structure and characteristics of electro-hydraulic and electromechanical active suspensions are introduced in detail. The bottleneck problems of active suspension structure for military vehicles are analyzed from the test results of electro-hydraulic and electromechainical active suspensions. The requirements of military vehicle active suspension for structural performance and the key bottleneck technologies are summarized, which are high power density, high reliability and low hysteresis actuator technology. A clear research idea of new active suspension structure is put forward: the innovative introduction of electro-hydraulic composite actuator can not only avoid the large time delay of electro-hydraulic active suspension and the inertial impact of electromechanical active suspension, but also realize the active suspension control.
