Fatigue Testing Machines | For Dynamic Testing
Fatigue testing allows manufacturers and researchers to get a critical understanding of how a material or component will perform in real-world loading scenarios over the course of time. ADMET offers a wide range of fatigue testing systems to suit your testing requirements. Higher capacities for each system can be accommodated based on customer needs. Speak with one of our sales engineers to learn more.
Electromechanical Fatigue Testing Systems
The eXpert 5900 series tabletop dynamic testing machine is a compact, quiet, and clean electrodynamic testing system for determining the durability of materials and components in tension, compression, or flexure.
eXpert 5900 series machines perform fatigue testing up to 15Hz in frequency and provide up to 14kN in load capacity. Custom designs are also available. The 5900 series actuators are a unique electromechanical design that features a direct drive bearingless motor, flooded bearing stack, and ball screw with continuous lubrication. This design greatly extends the life of the actuator and is ideal for performing cyclic tests at small or large amplitudes over millions of cycles. This makes Low Cycle Fatigue (LCF) and High Cycle Fatigue (HCF) tests a possibility up to the 15Hz range.
Torsion Fatigue Testing Systems
eXpert 9900 series Table Top Torsion Fatigue Testing Machines are available in vertical or horizontal orientations. Horizontal systems feature a fixed spindle with sliding tail stock while vertical systems employ a sliding drive spindle. Maximum torsional stiffness and minimal axial friction are achieved with a roller slide frame design. A reaction torque transducer can be mounted to the tail stock or a rotary torque transducer can be mounted to the drive spindle to accommodate a wide range of applications.
Biaxial Fatigue Testing Systems
The eXpert 8900 Axial-Torsion Fatigue Testing Systems is ideal for performing fatigue testing on specimens that require both a torsional and axial load. The system has a maximum dynamic force capacity of 17.5 kN (3,934 lbf) and maximum dynamic torque of 80 Nm (708 lbf-in). The eXpert 8900 has dynamic capabilities up to 20 Hz. ADMET engineers can customize the eXpert 8900 to meet your specific testing requirements. Click here to learn more about the eXpert 8900.
Servohydraulic Fatigue Testing Systems
Standard eXpert 1900 Series dynamic test systems are available in capacities from 10kN (2,250 lbf) to 250kN (56,000 lbf). Every eXpert 1900 Series tester is engineered to meet the force-stroke-frequency requirements of each application. Depending on the size of the hydraulic power supply (HPU), the 1900 Series HPU is either integral to the frame or free standing.

Controllers for Fatigue Testing Systems
Users of ADMET’s dynamic fatigue testing systems have a choice of two controllers: the MTESTQuattro high-speed closed-loop controller, or the DC1X Dynamic Fatigue Controller.
MTESTQuattro can be programmed to generate sine, square and triangular waveforms. Users can manually adjust control gains and endpoint values on the fly or activate amplitude control so that the controller automatically adjusts the endpoint values to ensure that the dynamic fatigue testing systems desired targets are met.
The DC1x controller is an ideal, cost-effective solution for basic cyclic fatigue testing applications. It is compatible with all ADMET servo-hydraulic and electro-mechanical dynamic test systems and can also be retrofitted to a wide variety of testing systems from other providers. It provides basic sine, square, and triangle waveforms. Amplitude control is a standard compensation program that tracks the feedback signal and automatically adjusts amplitude and setpoint control values until the desired peak and valley levels are achieved. This occurs continuously, ensuring all levels are within tolerance. It is ideal for cyclic tests under load control where test systems or specimen characteristics vary over time. During test, users can view peak/valley and the number of cycles completed.
Featured Configurations
