On Development of Testiiig and Traimiig Device forTechnical Background and Ability of Engineering Students

研究表明，锯切木制品过程中手掌和手指的测力变化与工科学生的技术背景和能力有关。根据这一观点，研制了一套技术背景和能力的测试与训练装置。对试件进行了专家、熟练使用者和初学者的手锯切割试验，结果表明：(1)工程师使用手锯的技能水平与手掌和手指的受力分布密切相关；(2)专家使用手锯时手掌的受力变化是有规律的。(3)参照专家的作用力模式对初学者进行了多次训练，提高了新手使用锯切时的作用力变化和技能水平。(4)该装置可用于测试和训练工人使用手锯切割时的技能。

In this study, it is shown that a measuring force variations of the palm and fingers during working to cut a wooden work piece with a saw is related to the technical background and ability of engineering students. According to this stand point, a testing and training device for the technical background and ability is developed. Some testing has done for cutting the test piece by the expert, the good user and beginners with a hand saw.Results obtained is as follows ;(1)The technical skill level of a engineer for the using a hand saw is closely related to the force distribution in the palm and fingers.(2) The force variation in the palm of the expert during using a saw changes regularly. However, it of t he beginner shows a irregular and suddenly changing one.(3)Number of training for beginners which is done referring to the force pattern of the expert improves his force variation and skill level in using a saw.(4)The device proposed is useful for testing and training the skill of workers during cutting by using a hand saw.
