Simulation Analysis Based On Virtual Prototype Of Modeling Vibration Table During Motive Process

Lost foam casting with unique craft, low environmental pollution, less manpower and of high quality casting are valued by more and more important foundry manufacturer, has a good development advantage. However, with the EPC in high speed development, there are some questions are difficult to overcome.Sand fill and compaction are essential factors of successful EPC, as well as the difficult point of successful EPC. Now, foundry workers pay less research on pattern of vibration table, and published in the journal papers and patents are request. So this topic use virtual prototyping technology for the simulation of vibration characteristics on the model vibrating table.First, established the vibration table three model, including the structure working principle of vibrating table, and calculation of the parameters, such as for simulation of vibration table laid a good foundation; Second, briefly introduced the virtual prototype technology, importing the three models to virtual prototype software for simulation; third, Carried out a series of vibration motor combination simulation, and analysis the simulation results; Finally, through the experiments to verify the results of simulation experiment.The simulation results show that:Two motors at the bottom of the vibration table synthetic rotated, the vibration of the vibration table centroid trajectory is long elliptic;Two motors at the bottom of the vibration table reverse rotated, the vibration of the vibration table centroid trajectory is a straight line; a motors at the bottom of the vibration table synthetic rotated,the vibration of the vibration table centroid trajectory is irregular long ellipse;Two motors on the side of the vibration table reverse rotated, the vibration of the vibration table centroid trajectory is a straight line;Two motors of 90° placed on the side of the vibration table reverse rotated, the vibration of the vibration table centroid trajectory is spiral;Two motors on the side of the vibration table reverse rotated, at the same time,two motors on the side of the vibration table reverse rotated,the vibration of the vibration table centroid trajectory is two directions synthetic;Two motors on the side of the vibration table reverse rotated, at the same time,four motors on the side of the vibration table reverse rotated,the vibration of the vibration table centroid trajectory is three directions synthetic;Two motors on the side of the vibration table reverse rotated, at the same time,two motors of 90° placed on the side of the vibration table reverse rotated,the vibration of the vibration table centroid trajectory is bumpy ellipse.According to the vibration of the vibration table centroid trajectory can be speculated that the sand flow in the sand, laid a solid foundation on sand to fill for complex castings tight study.
