中文摘要：

针对砂轮基体在超高速磨削状态下膨胀变形的问题,以控制砂轮基体膨胀变形和降低旋转应力为目的,对超高速磨削砂轮基体进行结构优化。在分析砂轮基体截面形状对砂轮性能影响的基础上,以直线和样条曲线为基本的构造线建立砂轮基体的参数化模型,进而实现了对砂轮基体结构的多目标遗传优化,优化后的砂轮基体在250m/s的磨削速度下,其膨胀变形和等效应力分别降到30.827μm和94.97MPa,与原有砂轮相比分别降低了25.67%和6.44%。

In order to rotation matrix control expanding deformation in ultra high speed gr ix of grinding wheel is optimized. Based on the analysis ed model of grinding wheel matrix is established by s -objective genetic optimization of grinding wheel matrix curve and thus the multi show that under grinding speed of 250 m/s, expansi optimized grinding wheel matrix respectively decrease to the original grinding wheel they are respectively reduced on deformation and 30. 827 μm and 94.9 by 25.67% and 6.44
