摘要: 文章依托可视化数据分析技术，解决机械设计基础课程中机构运动学、动力学理论抽象、难以直观理解的痛点问题，将虚拟样机等新兴技术深度融入传统机械课程，开发“问题背景–理论支撑–技术方案–实验数据”模块化的教学案例范式，覆盖齿轮传动、四杆机构、凸轮机构等核心内容，提供动态仿真、参数化分析等资源，使抽象概念可视化。将数据可视化与案例教学深度融合，构建“数据可视–动态仿真–实践验证”的教学体系，显著提升学生解决复杂工程问题的能力。通过案例库的开发，使学生能够直观理解齿轮啮合原理、四杆机构运动特性等核心理论知识，同时培养其数据分析和工程思维能力，提升课堂互动质量，最终达成提高课程教学效率、增强学生设计创新能力的目标，并为同类课程的教学改革提供可借鉴的实践经验。

Abstract: Based on visual data analysis technology, this paper addresses the challenges in the fundamental mechanical design course, where kinematic and dynamic theories are often abstract and difficult to visualize. It deeply integrates emerging technologies such as virtual prototyping into traditional mechanical courses, developing a modular teaching case framework structured around “problem context-theoretical support-technical solution-experimental data”. This framework covers core topics such as gear transmission, four-bar mechanisms, and cam mechanisms, providing resources like dynamic simulation and parametric analysis to make abstract concepts visually accessible. By deeply integrating data visualization with case-based teaching, a teaching system of “data visualization-dynamic simulation-practical verification” is constructed, significantly enhancing students’ ability to solve complex engineering problems. Through the development of this case library, students can intuitively understand core theoretical knowledge, such as gear meshing principles and the motion characteristics of four-bar mechanisms, while cultivating their data analysis and engineering thinking skills. This approach improves classroom interaction quality, ultimately achieving the goals of enhancing teaching efficiency and strengthening students’ design and innovation capabilities. It also provides valuable practical experience for teaching reforms in similar courses.
