The control system design and simulation analysis of pneumatic manipulator based on AMESim

摘要

This specialized pneumatic manipulator is designed and developed to adjust to the medium and small sized horizontal injection molding machine, in order to improve the flaws existing in the production, such as low manual efficiency, poor production environment and poor quality of products. To begin with, the pneumatic control and structure of the single-axis servo pneumatic manipulator is designed, and the manipulator prototype is developed. Then we use LMS. AMESim to establish the circuit model of the pneumatic control system, obtain key components data of simulation and verify the validity of the control system model by comparing the simulation results with test results. In the end, we explore and discuss the influence of throttle opening on the manipulator furthermore, find that with the increase of the throttle valve opening, the main arm speed rises, the opening from 2/10 to 3/10 is the most reasonable.
