断裂直径是玻璃切割机金属刀架的重要参数,直接决定玻璃切割机的工作性能。为精确得到玻璃切割机金属刀架的断裂直径,采用有限元法分析不同断裂直径、不同外载荷作用的玻璃切割机金属刀架结构等效应力,以及结构最大等效应力产生的位置。通过有限元法仿真确定了玻璃切割机金属刀架的断裂直径优选参数,为金属刀架的优化设计提供了参考。

The breaking diameter is an important parameter of the metal tool holder of the glass cutting machine,which directly determines the working performance of the glass cutting machine.In order to accurately obtain the breakage diameter of the metal tool holder of the glass cutting machine,the finite element method was used to analyze the equivalent stress of the metal tool holder of the glass cutting machine with different breakage diameters and different external loads,and the position in the structure where generated the maximum equivalent stress.Through the simulation via finite element method,the optimal parameter of the breakage diameter of the metal tool holder of the glass cutting machine was determined,which provided a reference for the optimal design of the metal tool holder.
