土动三轴仪轴侧向系统相位测试方法及数字式相位仪的研制

本文对土动三轴试验系统中轴、侧向之间存在的相位差及其测试方法进行了讨论和比较。并根据试验要求设计了能满足测试各种波形函数相位差的“过零触发式数字相位计”,讨论了工作原理,提出了设计思路、方法及注意的问题。

Mothod of Measuring Phase Difference of Lateral System for Dynamic Soil Triaxia1 Apparatus and Development of Digital Phase Meter

In this paper the phase difference of lateral system for dynamic are soil triaxial testing system is discussed and variant measurement meth-ods are compared, according to testing requirement “zero crossing triggering digital phase meter ” was designed, which can measure the phase difference of variant waveforms. In addition, the opration principle, the designing, and the noteworthy prlobems are presented.
