초록
In this paper, design of a recumbent bicycle for loading cargo is introduced as an application example of practical engineering. This device consists of a main frame due to the main load, an occupant seat considering the human body structural condition, a steering device(handle), a power transmission device (gear/chain, pedal, and crank), and a braking device (disk brake). In order to design and manufacture of the device, various subjects learned during the school year are reviewed and practiced. In particular, by designing the shape considering the load acting on the recumbent and the structural conditions of the human body, it is possible to understand the detailed mechanical mechanism as well as the understanding for the basic design. Through this case study, students can develop and enhance their creativity and practical skills for related industries by designing and manufacturing a real recumbent bike and, if necessary, industrializing these skills.
