本文叙述了在室温至-196℃范围内金属板,棒、片、丝小样品的杨氏模量测试方法及测试设备。所用方法分别为静电激发横共振法和静电激发悬臂梁共振法。对T_2、1Cr18Ni9Ti、Mo、LD_(10cs)等不同材料及规格的试样进行了测试,给出了该温度范围杨氏模量的数据,并对测试误差进行了讨论。 This article describes the Young’s modulus test methods and test equipment for small samples of metal plates, rods, sheets and filaments at room temperature to -196 ° C. The methods used are electrostatic excitation transverse resonance method and electrostatic excitation cantilever resonance method. T_2,1Cr18Ni9Ti, Mo, LD_ (10cs) and other samples of different materials and specifications were tested, given the temperature range of Young’s modulus data, and the test error are discussed.
