项目摘要

In this research, we developed the shape memory alloy engine car and passive walking toy as a new material and new energy teaching material. The main purpose of this study is to find the possibility of introducing the teaching material in a junior high school as a class of technology education actually.In the SMA engine car, shape memory alloy and pulleys are used as a main prime mover of the car. The engine can rotate using the properties that shape memory alloy can turn into straight-shaped as it gets in a hot water. The most characteristic part is the engine. To make the temperature difference between upper and lower pulleys as much as possible, the engine part is leaned about 45゜ from a chassis. Because the temperature difference between hot water and room temperature is the most important to make the engine rotate as fast as possible.The passive walking toy walks down a gentle slope due to the gravity force and the instability of equilibrium. For using the toy as a teaching material, we measured the cycle period of its walking, and analyzed the motion. And then, the influence of various elements in its walking was considered.To find the possibility as a teaching material, the engine car ans toy were actually introduced in the class of technology education in junior high school as a practical teaching. Through the manufacture, the students can get through the experience of difficulty and joy to use tools and learn not only the way of manufacturing it but also the knowledge of a metal properties, the way of using tools and its names.

本研究开发了形状记忆合金发动机汽车和被动行走玩具作为新材料和新能源教材。本研究的主要目的是寻找在初中作为一门技术教育课实际引入教材的可能性。在SMA发动机汽车中，形状记忆合金和滑轮被用作汽车的主要原动机。该发动机可以利用形状记忆合金在进入热水时变成直线形状的特性来旋转。最具特色的部分是发动机。为了使上下皮带轮之间的温差尽可能大，发动机部分与底盘倾斜约45゜。因为热水和室温之间的温差对于使发动机尽可能快地旋转是最重要的。被动行走玩具由于重力和平衡的不稳定而沿着缓坡行走。以该玩具为教材，测量其行走的周期，并对其运动进行分析。进而考虑各种因素对其行走的影响。为了寻找作为教材的可能性,将发动机车和玩具实际引入初中科技教育课中作为实践教学。通过制造，学生可以体验到使用工具的困难和乐趣，不仅学习制造工具的方法，还了解金属特性、工具的使用方法及其名称等知识。
