Fatigue testing machine USF-2000A

continuous-motioncomputer-controlledfor metallic materials

Overview
The USF-2000A performs materials fatigue testing at 20 kHz, enabling evaluation in the very-high-cycle fatigue (VHCF) range (approximately 10^9–10^10 cycles). Results for ~10^7 cycles can be obtained in about ten minutes, allowing rapid characterization of fatigue behavior.

Product type
Ultrasonic Fatigue Testing System

Features

• Accelerated fatigue-life evaluation of metals and other materials at a 20 kHz cycle rate.
• Very-high-cycle testing capability up to around 10^10 cycles; continuous operation enables 10^10-cycle tests to be completed in a few days.
• Resonance-condition testing generates significant stress amplitudes for economical high-stress testing.
• Constant stress-amplitude control via the supplied controller with PC-based software for test setup and monitoring.

Technical specifications

• Cyclic frequency: 20 kHz (ultrasonic operation).
• Target evaluation range: on the order of 10^9 to 10^10 cycles.
• Short test time for moderate counts: ~10^7 cycles obtainable in ~10 minutes.
• Capability to complete extremely high-cycle tests (examples: 10^10 cycles in several days under continuous operation).
• Testing under resonance conditions to generate high stress amplitudes.
• Constant stress-amplitude control via supplied controller and PC-based software.
• Intended use: fatigue testing of metals, composites (e.g., CFRP) and additively manufactured materials at ultrasonic cycle speeds.
