Title Design and analysis of a mechanical arm with two degrees of freedom
Abstract
The mechanical arm as an automation device of the process of automated production used used to grab or move materials, workpiece.It can replace human to do dangerous, boring and repetitive work, reduce human labor intensity, improve labor productivity, and reduce the waste caused by defective rate.The research and development of the mechanical arm directly affects the improvement of the automation production in our country, it is necessary to consider both economic and technical, so it is very meaningful to carry out the research and design of the mechanical arm. In this paper, the design idea and the overall design scheme of two degree of freedom manipulator are presented, and the selection of motor, the design of control scheme and the modeling and Simulation of mechanical and electrical system are presented. In this paper, we use the three-dimensional design software pro/E to design the parts of the manipulator, and use the Pro/E modeling , and to adjust and improve. Then put it into the ADAMS to carry out the dynamic simulation, the use of Matlab for mechanical and electrical system modeling. And the results were analyzed and evaluated.
