摘 要: 通过对磨片精磨区间隙内纤维的运动分析,讨论纤维在解离过程中的流动状态,阐述纤维的流体特性;根据流体力学的运动学原理对纤维流体的运动进行速度求解,得出磨片精磨区间隙内纤维流体的运动模型,并建立纤维流体在精磨区内的运动轨迹方程,利用Matlab绘出纤维运动的轨迹图像。研究表明,纤维流体在精磨区内的流动属于库特流动,并符合NAVIER提出的“线性滑移模型”;其运动轨迹呈螺旋线形,并受磨片转速、磨片间隙、磨片齿倾角的影响。
关 键 词: 机械设计;轨迹模型;流体运动分析;精磨;纤维分离

Abstract: Through kinematic analysis for fibers in fine grinding area clearance of refining plates, the flow states of fibers during separation were discussed. The fluid characteristics of fibers were described. According to the kinematic principle of fluid mechanics, the velocity of the fiber fluid was solved and the trajectory model and equation of fiber fluid in the fine grinding zone were established. The trajectory images of fiber fluid were drawn through the software Matlab. Results indicate that the flow of the fiber fluid in the fine grinding area obeys the Coutte flow and obeys “Linear slipping model” proposed by NAVIER. The trajectory of fiber fluid is spiral and influenced by speed, clearance and tooth inclination of refining plates.
Key words: mechanical design; trajectory model; fluid movement analysis; fine grinding; fiber separation
