摘要: 通过测量悬臂梁自由阻尼振动频率等参数来计算梁状材料的杨氏模量.实验通过精心设计,涉及并运用了力传感器、惠斯通电桥、数字存储示波器、计算机接口、快速傅里叶变换和LabVIEW虚拟仪器等知识和内容.

关键词: 杨氏模量, 悬臂梁, 数字示波器, LabVIEW

Abstract: The Yang's modulus is obtained by the measurement of free vibration frequency of a cantilever with damping. During the process, some comprehensive and researchful knowledge are concerned, which include force sensor, Wheatstone bridge, digital oscilloscope, computer interface, fast Fourier transform and LabVIEW virtual instrumentation.

Key words: Young's modulus, cantilever beam, digital oscilloscope, LabVIEW
