Project management for cooperative handicraft of low temperature differential model Stirling engine

Abstract

First grade students of Mechanical Engineering Program could not make low temperature differential Stirling engine within 270 minutes as a first year seminar. The 270 minutes means three 90-minute works. The prototype of the low temperature differential Stirling engine had been made by one person within 7 hours. The fail by the students may be caused by the papers showing the shapes of parts made of poly-vinyl chloride. The paper was designed for the paerson who made low temperature differential Stirling engine alone. Therefore, the pattern papers should be improved to promote a division of work. The project for 12 students to make a low temperature differential Stirling engine is planned. When the 12 students can use 3 hand drills, three 1.0mm-drill-bits, three 3.0mm-drill-bits, 3 countersink-drills, 3 scissors, 3 long nose pliers, 1 cutter knife, and 1 hacksaw, the planned project suggests the low temperature differential Stirling engine is made within 180miniutes. This 180 minutes means two 90-minute works.
