摘要
以工程实际中惯性回转振动机械常用的玻璃钢杆为研究对象,以杆上端固定、下端自由的铅垂悬臂梁为实验模型,采用敲击法测得玻璃钢杆的杨氏模量。研究结果表明,玻璃钢杆的杨氏模量与其自身长度有关,实验得到了长度为500 mm到1 000 mm时玻璃钢杆的杨氏模量,为该类机械的设计计算提供参考。
Taking glass steel suspender used widely in engineering as the research object, taking vertical cantilever beam whose upper extreme was fixed and the lower extreme was free as the experimental model, got the Young＇s modulus of the glass steel by using hammering method . The results showed that the Young＇s modulus of the glass steel suspender has relationship with its length, and got the Young＇s modulus of the glass steel sus- pender when the length were 500 mm to 1 000 mm, providing references for the design of such equipments.
