Vic-Gauge

 

技术概述 Technology Overview

vic-gauge-ss1Vic-Gauge使用CSI优化的2D和3D相关算法为力学测试提供实时位移和应变数据。该工具可被视为一组光学虚拟引伸计/应变仪：可同时监测多点的数据，并同步载荷的模拟信号进行实时的位移/应变-载荷曲线图绘制。过程中的每个数据点都可被保存，而全部图像也可被保存并在Vic-2D或Vic-3D中进行全场数据分析处理。

Vic-Gauge uses our optimized 2-D and 3-D correlation algorithms to provide real-time displacement and strain data for mechanical testing. Think of this tool as a set of virtual strain gauges: Data can be retrieved for multiple points and plotted live against analog load inputs. Results are saved for every analyzed point, and full images may be saved for full-field analysis in Vic-2D or Vic-3D.

该系统通过用模拟信号来实时输出测量数据，实现了以完全无损的应变测量方法来驱动和控制试验。 Vic-Gauge可以测量从50个微应变到5000％以上的任意应变和位移，试件尺寸从小于5mm到大于 5m不等。

Real-time analog output is also available, allowing strain controlled tests with a completely noninvasive strain measurement method. Vic-Gauge can measure arbitrary displacements and strains from 50 microstrain to 5000% strain and above, for specimen sizes ranging from <5mm to >5m.

由于设置简单，只需一台相机对试件进行成像，Vic-Gauge系统可轻松与几乎任何拉伸测试框架结合，且不需要特殊的照明或激光。

Because the setup is simple, requiring only a single camera imaging the specimen, the Vic-Gauge system can easily be integrated with almost any tensile test frame. No special illumination or lasers are required.

CSI公司的Vic-Gauge测量系统广泛用于聚合物、橡胶或生物组织等柔性材料的测试。该系统能够进行实时应变测量，并且可以与标准拉伸/压缩试验机及控制器连接。对于高应变率测试，CSI提供每秒可处理100,000个采样点/数据点的Vic-Gauge系统（通过后处理）。

Our Vic-Gauge system is widely used for material testing of compliant materials such as polymers, rubber or biological tissue. The system is capable of real-time strain measurement and can be interfaced with standard tension/compression test frames and controllers. For high strain rate testing, we offer Vic-Gauge systems capable of 100,000 samples per second (post-processing).
