物料沿抛送叶片的运动仿真与高速摄像分析
Dynamic simulation and high-speed camera analysis on materials moving along throwing impellers
摘要
Abstract
In order to reveal the relationship between the motion pattern of the materials and power consumption and throwing efficiency of an impeller blower, and further reduce its power consumption and improve its throwing efficiency, the motion pattern of the materials moving along the throwing impeller was studied based on the high-speed camera technology combining with the theory analysis and virtual prototyping. Its dynamic equation was established and the moving pattern of the materials was numerically simulated in ADAMS. They can be applied to various mounting angle of the throwing impeller. Moreover, the equivalent friction coefficient obtained through regression analysis on the data acquired by the high speed camera was used to correct the dynamic equation and ADAMS simulation model for the sake of considering the interaction between the air flow and the materials as well as the interaction among the materials comprehensively. In addition, the optimal range of the material-throwing angle was established to be 60°-130°. All the results will play a significant role in carrying out the parametric optimization of the impeller blower in the future.关键词
