颗粒材料振动实验仪研制

摘要

The stress of granular materials, especially the stress relaxation of granular materials under vibration,is less studied.In order to observe the vibration regularity of granular materials,a vibration experimental instrument for particle materials is developed.The materials can be pressed as required to produce an image of stress and to make the particles vibrate at certain frequency.%对颗粒材料的应力尤其是振动下颗粒材料应力松弛现象研究较少.为了便于观察颗粒材料的振动规律,研制了颗粒材料振动实验仪,可以按要求对材料施压,将应力生成图像,而且能够使颗粒按一定频率振动.
