动三轴仪(循环三轴仪)美国GEOCOMP

美国GEOCOMP应力路径三轴仪简介

用途：

循环三轴系统由LoadTrac II加载架和

FlowTrac II流量泵组成，该系统可以全

自动完成土的循环(动)三轴试验，例如

土的动强度试验与砂土的抗液化强度

试验，从而得到土的动强度参数或剪切

模量与阻尼比等。

环球香港科技是美国GEOCOMP在中

国的唯一的，独家代理。

概述：

LoadTrac II + FlowTrac II循环三轴试

验系统包括：安放试样的三轴压力室、

计算机控制的加载架、计算机控制的分别施加围压和反压的两个液压泵、提供循环加载的高性能线性的伺服作动器（更新速率为每秒500次）、精确控制循环加载的微处理器、以及控制试验并采集数据的电脑。

特点：

技术参数：

cyclic triaxial testing of soils. Minimum man-time is required.

The LoadTrac II/FlowTrac-II Cyclic consists of a triaxial cell to retain the sample, a load frame with computer-controlled platen for static loading, two

computer-controlled flow pumps to control chamber pressure and back pressure, a high performance linear actuator servo control actuator for cyclic loading with update rates of 500 times per second, a micro-processor for accurately controlling cyclic loading, a PC with a Pentium processor to control the test, and to log test data. Editing and reporting is built-in to the test and control software program. The unit arrives in a completely self-contained system with all necessary equipment.

The LoadTrac II/FlowTrac II Cyclic system is menu driven. The Windows® XP, Vista, 7 based software allows users to define the conditions for running the test, logging test data and reporting results. Users can specify the values for controlling the saturation, consolidation and cyclic loading of a test. During testing, current data and system status information is displayed. Collected data are written to a file on the system's hard drive. The reporting software performs all required calculations and permits users a variety of options in graphing and generating test data.
