Design 6-DOF fatigue life test system for vehicle driver seat

Vibration fatigue test system for vehicle driver seat is developed to aim at fatigue failure driver seat. The implement structure and control technology of synchronal record and representation of motion and video are introduced in this paper. The method of synchronization display of motion and video by wired communication is developed. The six degree of freedom hydraulic-servo motion base as an experimental research device is applied to test vibration fatigue of vehicle driver seat. The results of experiment verified its feasibility to develop a new product test of vehicle driver seat.
