摘要
为了开阔学生的工程视野,培养学生解决工程问题的能力,针对船舶、汽车、机械等行业需测定物体重心位置的需求,结合大连理工大学相关专业的特点,设计了一种测定物体重心坐标的实验教学装置并得到了应用。该教学装置运行稳定、易于操作,实验结果与理论计算值相一致。该设备的教学应用丰富并完善了基础力学实验的教学内容,取得了良好的教学效果。
In order to broaden students’engineering vision and develop their ability to solve engineering problems,this paper designs an experimental teaching device for measuring the coordinates of the gravity center of objects.This device meets the needs of the marine,automobile,machinery,and other industries to determine the position of the gravity center of objects,and also takes into account the characteristics of relevant majors of Dalian University of Technology.The teaching device is stable and easy to operate,and the experimental results are consistent with the theoretical calculation values.The teaching application of the equipment enrich and improve the teaching content of basic mechanics experiments,and achieve good teaching results.
