| Abstract: |
| The work aims to optimize the dynamic characteristics and improve the feeding efficiency by conducting the simulation research on the vibration feeding process, for the purpose of ensuring the working reliability of vibration feeder under various complicated working conditions. Starting from the excitation mode of the vibration system, the dynamic reliability of two excitation modes (motion excitation and force excitation) was analyzed and compared. On the basis of that, the vibration feeder based on the forced motion excitation of the crank slider mechanism was the object of the research. A three-dimensional assembly model of vibration feeder was established with SolidWorks, and the establishment of the relevant simulation model and its parameter test and optimization were completed in ADAMS. The crank speed and crank length had obvious influence on feeding efficiency. By means of simulation, a set of optimal parameter values of crank speed (376 r/min) and crank length (12.85 mm) in the crank slider mechanism of vibration feeder were obtained. The simulation test and its optimal design of the crank speed and crank length have improved the feeding efficiency of vibration feeder. |
