The Finite Element Analysis And Simulation In Air-flow Field Of Grinding Area

With the development of grinding technology, the grinder is playing the more and more vital role in the manufacture industry. Because the modern industry is more and more high to the workpiece quality request, so how to enhance grinding technology has brought to the attention of many countries' scholars. In the grinding process, the air-flow field in grinding zone has influence on the quality of workpiece. This is because in the grinding process, the surface of workpiece would focus on much heat. To reduce the temperature we must supply the coolant to the grinding area. But the air-flow field makes much fluid not entrance the grinding area. So we must find out and master the features of the air-flow field in order to find solution to overcome its influence, enhancing the use rate of the cooling fluid. Therefore the study of the fluid has quite important signification.In the article, we study air-flow field, based on the hydromechanics, used the technique of numerical simulation, used the software ANSYS, established the FEM of the air-flow field, has been carried on under the different conditions. I.e. changing the velocity of the grinding wheel and the gap between grinding wheel and workpiece. We have computed the pressure and velocity with pressure contour and velocity contour gotten. We come to conclusion of the air-flow field and the influence of the grinding speed and the clearance on the air-flow field, which will be used to guide the application study of grinding and high-speed grinding.The study indicated that the higher the speed of grinding, the bigger the maximum pressure of air-flow field. The smaller the gap between the grinding wheel and workpiece, the bigger the maximum pressure of air-flow field and the reverse velocity of air-flow.
