英文摘要：
Friction Stir Welding (FSW) robot equipment with high performance has become an important development direction of friction stir welding technology and high-tech welding equipment, with overpowering demands in the fields of the aerospace, rail transportation, automobile and ship manufacturing. In this project, inertia feed-forward control and high precision welding of FSW robot will be realized by the fusion of the rigid driven and cable driven characteristics, dealing with innovation design and key technology research of redundant driven and rigid-flexible cooperation FSW robot equipment, inventing a kind of adjustable double stationary shoulder stirring head structure, constructing precise dynamics model of redundant driven multi-body system considering the nonlinear dynamic characteristics. One carry out multi-objective dimensional synthesis in coordination with considering both structure system and control system integrated design. A new compound control strategy based on the combination of inertia feed-forward control and PID servo feedback control is proposed, which achieve inertia feed-forward control and high precision welding of FSW robot. Through the above researches on establishing a new and high efficiency design method in term of redundant driven and rigid-flexible cooperative FSW hybrid robot equipment and regarding high-speed rail EMU and other rail vehicle manufacturing as an application objection, which can develop a novel FSW robot equipment experimental prototypes to conduct an experiment and application test as well. It can not only expand the innovative application of robot technology in the field of high-tech equipment manufacturing, but also improve the urgent requirement to the level of welding manufacturing industry.
