掘进机在工作时所能截割出的最大尺寸是设计掘进机的一个重要参数。根据掘进机截割工作原理及特性,应用建模软件构建实体模型,采用三维模型技术对掘进机截割断面进行计算,计算结果用来检验设计数据是否达到理想目标。 The maximum size that a boring machine can cut at work is an important parameter in designing a boring machine. According to the working principles and characteristics of roadheader cutting, a solid model is constructed by using the modeling software, and the cutting section of the roadheader is calculated by using the 3D model technology. The calculation results are used to test whether the design data meets the ideal goal.
