Most mechanical failures occur due to the repeated application of stress over time. TRI’s Fatigue and Dynamic Testing systems are designed to evaluate long-term endurance and operational reliability, simulating millions of cycles to determine the definitive endurance limit of materials and finished assemblies.
High-Cycle Endurance & Reliability
While many test machines focus on static strength, TRI dynamic frames specialize in High-Cycle Fatigue (HCF) and durability studies. Our systems are engineered for high-volume repetition and high-stability control without the complexity of traditional servohydraulic components.
- Frequency Range: High-stability control from 0.1 Hz to 20 Hz (optimized for sustained performance at 15 Hz).
- Waveform Profiles: Smooth sinusoidal cyclic loading ensures consistent, repeatable stress amplitudes over millions of cycles.
- Load Capacity: Precision dynamic loading up to 50 kN via our standard modular actuators.
Dynamic Characterization & Analysis
Beyond life-cycle testing, TRI systems allow engineers to analyze how material properties change while in motion – a critical factor for polymers, damping components, and medical implants.
- Dynamic Stiffness: Measuring the overall resistance of a component to cyclic deformation.
- Phase Lag: Analyzing the time delay between applied load and material response to calculate damping coefficients.
- Energy Dissipation (Hysteresis): Calculating energy lost as heat during each cycle, essential for vibration isolation and shock absorption analysis.
Common Standards Supported
TRI dynamic systems execute protocols for ASTM E466 (Force-Controlled Fatigue), ASTM F1717 (Spinal Construct Fatigue), and ISO 14801 (Dental Implant Fatigue).
