Development Of A Drive Device For A Rocket Booster

Liquid core stage solid booster rocket is bundled using a hot research rocket, one practical question is, how will weigh tens of tons of solid rocket boosters and the core stage safely and reliably assembled, is needed to solve practical engineering problems. This paper is aimed at the practical problems of a certain type of rocket booster assembly of the drive program study design.First, according to the general process means the development of analysis and design task book, put forward a proposal, analysis program, a comprehensive program of improvement identified a booster hydraulic integration of intelligent drives. To design the shape and the relationship between the various components of the drive between. Through analysis and calculation of the design task indicators, the link mechanism, fixed hydraulic cylinders, linear guides, synchronous servo motor and ball screw are calculated selection, and check whether they meet the design requirements of the drive.Secondly, the overall design of the drive control system to build a framework, and the main control hardware and control system software program is designed. Among them, the main hardware circuit design, including preliminary functional design DSP smallest unit circuit, a data interface system circuit and servo motor function of the circuit.Finally, the driving device sports area and boundary conditions, transition conditions, trajectory planning method is proposed interpolation method based on the establishment of a 4-3-4 type three polynomials radial motion trajectory of the drive layer, simulation in Matlab generated track. After the trajectory generation, we need to verify the AC servo system can track the trajectory, the first of AC servo system radial motion layer mathematical model, while using the control method of synovial adaptive backstepping, trajectory tracking servo system ability to carry out simulation.
