描述并验证了超声法测量有限尺寸样品的材料弹性常数的方法。基于声学显微镜技术，利用研制的线聚焦PVDF换能器超声系统，通过同时测量纵波和泄漏表面波速度，确定了材料的弹性常数。本文对0.2 PZN-0.8 PZT压电陶瓷圆片样品有限尺寸掺杂Cr2 O3的弹性常数进行了测定，并对测量误差进行了分析。实验结果表明，该超声系统可用于有限尺寸样品的材料弹性常数测量，测量精度高，泊松比和杨氏模量测量的相对误差分别小于1%和3%。它可以满足工程和科学研究的需要。此外，所研制的超声测量系统适用于各向同性和各向异性材料弹性常数的超声测量。
Measurement of material elastic constants for limited-size samples by ultrasonic method is described and validated. Based on acoustic microscope technology, the material elastic constants are determined by longitudinal wave and leak surface wave velocities simultaneously measured by developed ultrasonic system with a line-focus PVDF transducer. In this paper, the elastic constants of limited-size Cr2O3doping on 0.2 PZN–0.8 PZT piezoelectric ceramic wafer sample are determined and the measurement errors are analyzed. The experimental results show this ultrasonic system can be used for measurement of material elastic constants for limited-size samples with high measurement precision, and the relative errors for Poisson’s ratio and Young’s module measurements are, respectively, less than 1% and 3%. It can satisfy the requirement of engineering and science research. Furthermore, it is suitable to measure elastic constants of both isotropic and anisotropic materials by ultrasonic method with help of developed ultrasonic system.
