【摘要】 从量程控制、频率匹配、传感器种类和精度的选择等三个方面分析了甄选HCA仪的主要要素。同时对目前国际上具有代表性的一些空心圆柱仪在试样尺寸、加载能力和测量精度以及工作频率等方面的性能进行了比较,并着重强调了其在研究主应力轴旋转问题中的工作能力,这些分析对比工作对研究者根据自身的试验要求来选购和开发同类仪器具有参考价值。更多还原

【Abstract】 A analysis on the factors of selecting hollow cylinder apparatus has been done from three aspects,such as range control,frequency matching,selection of types and precision of transducers.In addition,the comparison on the performance index of hollow cylinder apparatus,which are typical of the same kinds in the world has also been done.And the index include sample size,loading capacity,work frequency and so on.The emphasis is put on the work capacity during principal stress ratation.This will serve as reference for the researchers to choose and develop HCA for the special subjects.更多还原
