With Flexible Belt Drive Mechanical System Dynamics Modeling And Simulation Research

Recently there are so many researches about the rigidity Mechanical dynamics, and some in-depth researches about the elasticity mechanical dynamics, but little research about the flexibility mechanical dynamics, especially the influence on speed fluctuation of machinery while the mechanical system includes the flexibility machine. Using experimentation, dummy imitation and the method conjoint the dummy with actual the mechanical dynamics is studied in this paper. Deeply discuss the influence on speed fluctuation of machinery about the elasticity transfiguration and comparatively slippage while the mechanical system includes the flexibility machine.Through the machine kinematics and dynamics knowledge, the paper researches the relationship between the force act on the machinery and mechanical movement, and seeks movement rule of mechanical speed fluctuation from the movement process. According to the teaching instrument named JST-A experiment table for mechanical system movement analysis and speed fluctuation adjustment that is ready made, we set up the machine dynamics model, and calculate the various variable and parameter, then carry on the simulation of movement rule of the speed fluctuation using the Matlab software. And obtain the general movement rule curve of the rigidity machine simulation, In addition, consider the influence on speed fluctuation of machinery while the mechanical system includes the belt drive, and find the actual rule of the mechanical movement process further more. Use the Matlab simulation again, and found that it is not neglectful influence on speed fluctuation of machinery from the drive system. of the mechanical system. Finally, using Visual Basic language writing test program for the experiment table, gather the actual experiment data, and trace the curve, then we can obtain real movement law of the mechanical system. Comparing with the simulation results, draw the conclusion.
