摘 要:针对涡街流量计教学存在课堂教学不够直观、理论知识抽象难懂的问题,提出一种基于三维动画的教学方案。该方案实现主要经过3个步骤:三维模型构建、各部件分解展示及三维动画合成。首先,利用3ds Max建立检测放大器、表体和连接杆等器件模型,然后利用三维动画技术对液体涡街流量计各部件组成结构进行分解展示,最后将声音、文字、背景音乐内容经Adobe Premiere合成三维动画,并完成液体涡街流量计教学知识的详细讲解。该新式教学方法更加直观、形象,相较于原本枯燥的书本教学,能够提高学生学习热情,达到良好的学习效果。

Abstract:Aiming at the problems that vortex flowmeter teaching is not intuitive enough and the abstract theories are difficult to understand, we propose a teaching scheme based on three-dimensional animation. The teaching program mainly involves three steps: the construction of three-dimensional model, the decomposition of various components and the synthesis of three-dimensional animation. First, we use 3ds Max to build a device model of the detection amplifier, the body, the connecting rod and so on. Then, we present the components of the liquid vortex flowmeter decomposed through three-dimensional animation technology. Finally we process sound, words and background music by Adobe Premiere to synthesize three-dimensional animation and realize complete detailed analysis of liquid vortex flowmeter teaching.The new teaching is more intuitive and vivid, which can improve students enthusiasm for learning to achieve good learning results compared to the original boring teaching.
Key Words:liquid vortex flowmeter; 3ds Max; Adobe Premiere; 3D animation

流量是工业自动化领域的重要检测参数之一。涡街流量计在流量计量中应用广泛,主要应用于石油化工、治金机械、煤炭交通、食品、造纸,以及城市管道供热、供水等领域[1-4],在计量相关专业教学中具有重要地位。因此,必须深入掌握其结构形式、特点、测量原理、参数整定、信号检测、调整和校验方法等知识。
学生对涡街流量计的学习大多是通过书本这种传统方式,以文字描述流量计组成结构、测量原理和流体流动形式等。该方式缺乏直观性,单纯的文字描述十分枯燥,难以激发学生兴趣,无法达到理想的教学效果。因此,采用正确的教学方法对于学生而言尤为重要[5]。张兰红等[6]将Proteus仿真技术引入单片机教学过程,采用软硬件结合的教学方式,实现仿真教学系统开发;……
