GDSVIS加载系统升级-新设计和新软件相结合
GDS虚拟无限刚度加载试验系统Z近经历了一次升级改造,包括更新了系统外观设计以及更新软件。GDSVIS是GDS系列中Z重要的加载系统,荷载范围包括100, 250, 400 以及 500Kn。GDSVIS的设计使其刚度高于其他经典荷载架。从而能更精确地测试较硬的样品减少设备依从性。此外,每个GDSVIS都能做内部校准,允许自动补偿残余的依从性。

主要特征及优点:
| Key features | Benefits to the user |
|---|---|
| Load-deformation relationship: | The GDSVIS is calibrated to provide precise data on the load-deformation relationship of the entire load application and load measuring system, which is then automatically used for self compensation. |
| Built in feedback: | All VIS frames have feedback control and continuous display of axial load and platen displacement to allow simple and confident control of force and displacement. |
| Automatic correction: | VIS provides automatic correction for system compliance, a common cause of error, which can under-estimate results of sample stiffness. |
| Column strength: | The 500kN load frame has been built with 4 columns for extra strength and rigidity and can hold a cell size with a 700mm outer cell diameter. |
| Electro-mechanical actuators that give superior performance, reduce space and provide cost savings: | Electro-mechanical actuators can carry out tests with greater accuracies than comparable pneumatic actuators. Mains powered means no external noisy power packs and opposed to pneumatic systems electro-mechanical systems draw only the power that is required. |
| Standalone Control: | The GDSVIS load frame can be controlled via the keypad in terms of load or displacement with no requirements for a data logger or control PC and software. |
| Mechanical upper beam lift as standard: | Lead screw based lift system for the upper beam. Which, eases movement and positioning of the cross beam. |
| Advanced Trajectory generation: | Ensures smooth transition between current trajectory and a new target trajectory. |
