摘　　要：通过数值建模的方法研究结构化砂轮的磨削性能可以清晰地展现其复杂的磨削机理,并且能够设计出符合实验要求的结构化砂轮,进而提高磨削实验效率。本文通过建立砂轮和螺旋线的坐标系,分析两者的数学关系,沿螺旋线在砂轮圆周方向上构建大螺旋角沟槽砂轮的数值建模研究,提出了一种更简便地构建螺旋沟槽砂轮的数值建模方法。The study of the grinding performance of structured grinding wheels by means of numerical modelling enables the complex grinding mechanism to be clearly presented and allows the design of structured grinding wheels to meet the experimental requirements,thus improving the efficiency of the experiments.In this paper,a numerical modelling study of a large spiral angle grooved grinding wheel is constructed along the spiral in the direction of the circumference of the wheel by establishing the coordinate system of the grinding wheel and the spiral and analysing the mathematical relationship between the two.A simpler method is proposed which allows the construction of spiral grooved grinding wheels directly from numerical modelling.
