摘　　要：为了确保高速/超高速砂轮的安全性,对砂轮的受力进行了系统分析。认为砂轮工作时,砂轮的安全性主要受离心力的影响,整体式高速砂轮应以校核砂轮的抗拉强度为主,而超高速分体式砂轮应以控制基盘的径向膨胀量为主。并以ANSYS软件为辅助工具,分别对砂轮基盘的形状、材料、孔径比进行了分析和选择。最后,以最小径向膨胀量为目标函数,在200m/s的转速下,对钛合金梯形基盘的截形进行了最优化。In order to insure security rotation of high/ultra-high speed grinding wheel, the force characters of the wheel were analyzed systematically in this paper. Centrifugal force is primary effect factor for security work, whole baked high speed wheels ought to verify mainly tensile strength ,and split-type adhesion ultra-high speed wheels ought to control mainly radial displacement. The paper also analyzed and chose the shape, material ,ratio of the internal radius to the external radius of the wheel hub based on ANSYS software. At last,the taper shape wheel hub of titanium alloy was optimized at 200m/s.
