中国科学院武汉岩体土力学研究所最近研制成功二项岩石力学测试的仪器设备,经过鉴定,认为各有一定特色和独到之处,对推动有关方面的科研工作具有现实意义。例如蔡忠理等同志研制的“82-01型岩石超声横波换能器”,由于突破了陈旧的设计思想,合理地选用了压电材料和压电晶片的尺寸比,发挥了外壳的机械力学特性;从而增强了主剪切振动的振幅,能够准确地判读横波的首波初至时间,为横波换能器闯出了一条新路。本刊限于篇幅,这里仅刊登摘要,原文将在《岩土力学》陆续发表。
The Institute of Rock and Soil Mechanics, Chinese Academy of Sciences recently successfully developed two rock mechanics test equipment, after identification, that each has its own characteristics and uniqueness, to promote relevant scientific research has practical significance. For example, the “Type 82-01 ultrasonic ultrasonic shear transducer” developed by Comrade Cai Zhongli, etc., broke through the obsolete design idea and rationally selected the size ratio of the piezoelectric material and the piezoelectric wafer to exert the mechanical and mechanical properties of the shell. Thus enhancing the amplitude of the main shear vibration, accurately interpreting the first arrival time of the first wave of the transverse wave and breaking a new path for the transverse wave transducer. This article is limited to space, here is only published in abstracts, the original text will be published in “Geotechnical Mechanics” one after another.
