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 3900 and 5900 series table top dynamic testing machines are compact, quiet, and clean electrodynamic testing systems for determining the durability of materials and components in tension, compression or flexure. eXpert 3900 series machines feature efficient brushless linear motors with high accelerations, exceptional accuracy, and repeatability and are well suited for a wide range of biomedical and composite testing applications.
eXpert 5900 series machines perform fatigue testing up to 10Hz in frequency, and provide up to 14kN in load capacity. Custom designs are also available. The 5900 series actuators are a unique electromechanical design which feature 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 10Hz 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 is 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.
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 end point values on the fly or activate amplitude control so that the controller automatically adjusts the end point 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 system or specimen characteristics vary over time. During test users can view peak/valley and number of cycles completed.
