The Design And Characteristic Studies Of Digital Valve Cylinder Motion Platform

6 DOF motion platform is a parallel mechanism, the upper and lower platforms, and six retractable actuator and the hinge connections between them constitute the next platform, usually a fixed platform, the platform for moving the load moving platform, by control the movement of the six actuators on the platform parameter to achieve the six degrees of freedom motion control. Six freedom motion platform with a simple structure, good rigidity, high precision, Dongtaixiangying Kuai so good characteristics, especially for Yu high precision and large load space and Gongzuo smaller occasions, is widely used in machine tool, simulator, Jing Mi positioning and so on.The subject aims to design a stepper motor used as the electro - mechanical signal conversion device of the digital valve actuator cylinder to six degrees of freedom motion platform. Six degrees of freedom motion platform in the structure and motion analysis, based on through research, access to relevant information, complete the design of the digital valve cylinder, respectively, using AMESim and Simulink software to establish a digital valve cylinder model and the controller model, joint simulation, simulation with satisfactory results.For the design of the digital valve cylinder and the motion of the platform,it required to complete a micro-controller hardware and software design to achieve high-power movement of the platform control requirements.Six degrees of freedom motion platform to verify the intended movement equirements and load requirements, using Pro / E software to build a six-DOF motion platform, the virtual prototype, by Mechanism / Pro interface, interference in ADAMS, exercise testing, prototype model to the desired six degrees of freedom required without the risk of interference. And limits the number one position under the cylinder valve to test the maximum load, the results meet the design requirements, but also verify the digital valve cylinder design is reasonable. And for the spiral movement of the platform kinematics and dynamics simulation, simulation results show that the requirements meet the design parameters.
