Coesfeld Tear Fatigue Analyzer
Electrodynamic testing machine for dynamic crack propagation and fatigue tests, as well as static creep tests, with fully automated recording of the measurement cycles
Technical Specifications:
- Dynamic drives (2 stroke-controlled electric linear motors)
- Max. force: ±3.5 kN dynamic, ±2.1 kN static
- Stroke profiles: Sine, Gaussian, user-defined
- Stroke: ≤ 50 mm (shorter at high test frequencies) (Tolerance: ±1 µm)
- Test frequency: 0.1 to 100 Hz
- Force-controlled motors at each measurement position
- Control for constant force on the specimen despite increasing strain
- Max. force: 0.5 kN / 1 kN (5 motors/measurement positions each)
- Stroke: ≤ 50 mm
- Creep tests Preload: 0.5 kN / 1.0 kN per measurement position; 1.6 kN across 5 measurement positions
- Crack propagation measurement using a controlled, movable infrared camera
- Clamping distance: > 3 mm
- Test modes: Cyclic crack propagation and fatigue tests, as well as static creep tests
- Temperature chamber: -50 °C to 150 °C
- To prevent fogging on the windshield, the double-glazed door can be pneumatically flushed
