The Dynamic Behavior Analysis of Planar Linkage
Abstract: This paper analyzes the motion of planar four-bar linkage at first, then it analyzes the motion of planar six-bar linkage. After that ,it does analysis of the dynamic performance of plane six-bar linkage. Finally, it simulates the campaign of planar four-bar linkage and plane six-bar agencies, using a simulation software -- visual basic 6.0.
After systematically and analyzed plane four-bar and plane six-bar linkage in depth, we obtained the campaign performance of planar linkage mechanism. By this we achieved the purpose of analyzing the dynamic behavior of planar linkage mechanism. In order to make the study results more vivid and to obtain the linkage’s campaign curves and other related results ,we use visual basic 6.0 to simulate the campaign process of plane four-bar and plane six-bar linkage mechanism. The main special features in each design progress lieutenant general and will apply deluxe language Microsoft Visual Basic of calculator in great quantities, to imitate planar four-bar linkage mechanism and planar six-bar linkage mechanism to get analytical process of the kinetics of the linkage mechanism, include the establishment move control formula and reach agreement formula two parts. Principle of imitate is ask for help from linkage mechanism design of resolution method, make use of clock to control a piece to come to circulating change straight line or sit a mark roundly, carry out an animation to imitate true function。 Meanwhile, we can further analyze and examine the correctness of planar linkage’s displacement, velocity and acceleration and other characteristics. Through these above we can get the mechanical properties of planar linkage, and so as to achieve the purpose of this paper.
