Research And Design Of The Precise, High-speed Motion Control System On Electronic Elements Mounting Device

The subject is a part of SMT2520 research and development project.The subject uses Virtual prototype. In ADAMS, uses physics information and geometry information of each component which supplied from CAD system. Then define the connect relation of component in computer, and assemble the mechanic system that can get the virtual model machine of mechanic system. Make the simulation in ADAMS to verify the model.Make the co-simulation with Matlab Simulink and ADAMS. In Simulink environment the controlled object is the mechanic system model which built from ADAMS. With the real-time communication between the two soft wares, we can simulate the real moving detail in the virtual environment and analyze the motion and stress situation, observe and test the sliding beam's motion situation. That will be a theory base of the following solution creation, system improving and seeking of the optimum design.The sliding beam of sliding-beam-style SMT (Surface Mounting Technology) machine is the vital part of the whole mechanic system. It relates with precision allocation of mounting head, the rapid response and stability of system. The thesis analyzes the vibration problem of sliding beam high-speed moving and structure of the system with ANSYS. Use the modal analyzing to get the natural frequency and the vibration style at every step of the different shape beam, which are listed with tables and graphs. Based on them, we use ANSYS Optimization Design to conclude the relationship between the shape of beam and the modal frequency at the 1st step. In the end a set of shape parameters which can coordinate demand between frequency and weight of the beam is listed.
