A separation control method for a flight vehicle is presented. The difficulty of the control system of the flight vehicle lies in the sequential control in the separation process. Through test on the electromagnetism characteristic of the electromagnetism sucker and the electro-magnet, finally proposes one kind of reliable sequential control plan. Experiment proved, the control system designed performs...
To reduce the width of the gap between the steel sheets will be welded by laser to form tailored blank, roller forming process by plastically deforming the thicker sheet is presented. Mechanism scheme and working principle of the roller forming device are introduced. Mathematical model of roller forming is founded by experiment and function fitting. Rolling and welding experiment results show that...
