摘要/Abstract

摘要： “职业技能鉴定（钳工）”是针对铁道车辆钳工考证的一门专业拓展课程,课程实践性强,但铁道车辆存在机械装置体积大、重量大、难分解、难组装等问题,传统的教学方式难以有效解决机械结构难理解与实践操作高要求之间的矛盾,基于3D情景建模的教学方法充分利用3D扫描和3D打印技术,实现了线上线下资源交互映射,加深了学生对内部结构的认知,提高了学生的动手操作能力,提高了技能考试的合格率。

Abstract: Professional skill appraisal (machinist) is a professional development course for for obtaining railway vehicle machinist certificate. The course is highly practical. However, there are some problems in railway vehicles, such as large volume, heavy weight, difficult disassembly, difficult assembly and so on. The traditional teaching method is difficult to effectively solve the contradiction between the difficult understanding of mechanical structure and the high requirements of practical operation. The teaching method based on 3D scenario modeling makes full use of 3D scanning and 3D printing technology to realize the interactive mapping of online and offline resources. The teaching method deepens students' cognition of internal structure, improves their hands-on operation ability, and improves the passing rate of skill examination.

Key words: Digital Twins, Scenario modeling, Interactive mapping, Professional skill appraisal (machinist)
