Aimed at the problem of driver seat damaged during its use, life-span test system for vehicle driver seat was designed. The implement and control technique of six-degree of freedom synchronal record and representation of motion and video were introduced, and the method of synchronization play of motion and video by wired communication was developed. Using six-degree of freedom motion base as an experimental research device, applying control technique of the motion and video synchronal record and representation, the experiments of life-span for vehicle driver seat have been carried out. The experimental results verified that the life-span test system is feasible to develop a new vehicle seat.
