论文摘要
通过非接触声音测量研究了Kiwifruit的机械性能。使用静态激光源和旋转激光超声检测器测量传输的超声波。测量值可以观察到低频表面波和更高的频率直波；与地震学启发的理论建模相结合，这些测量值可以估算内部和外部果实层的几种弹性参数。结果表明，表面和直率波速度以及散装和杨的模量都随着果实的年龄/成熟度而演变，而外部和内部果实层之间只有直接波速度和散装模量有显着差异。
The mechanical properties of a kiwifruit are investigated via non-contact acoustic measurements. Transmitted ultrasonic waves are measured using a static laser source and a rotating laser ultrasound detector. The measurements enable observation of a low-frequency surface wave and a higher frequency direct wave; combined with seismology-inspired theoretical modeling, these measurements enable estimation of several elastic parameters for inner and outer fruit flesh layers. Results indicate that the surface and direct wave velocities and the bulk and Young's moduli all evolve with fruit age/ripeness, while only the direct wave velocity and bulk modulus differ significantly between outer and inner fruit layers.
