WDW-PWS Servo Hydraulic High Frequency Fatigue Testing System
INDUTECSA · SKU indutecsa-WDW-PWS-100
High-frequency servo-hydraulic fatigue system made up of a loading frame, a hydraulic power unit, test fixtures and a dynamic controller. It runs dynamic tension, compression, bending, fracture and crack-propagation (COD) tests and, by changing fixtures, static tension, compression, bending and shear tests, as well as component tests and fatigue-aging tests. It has a lower actuator with an internal LVDT transducer, self-centering hydraulic grips, and a front control panel with an emergency stop.
