Fatigue Universal Materials Testing System

Instron offers a comprehensive range of fully-integrated dynamic and fatigue testing systems, ranging from 1000 N to 5000 kN. Utilizing servo hydraulic, servo-electric, and linear motor technologies, these testing instruments support a wide variety of fatigue, dynamic, and static testing applications. These include high-cycle fatigue, low-cycle fatigue, thermo-mechanical fatigue, fracture mechanics, crack propagation and growth studies, fracture toughness, bi-axial, axial-torsional, multi-axial testing, high strain rate, quasi-static, creep, stress-relaxation, and many other dynamic and static test types.

Instron's entire range of Dynamic Testing Systems utilizes our state of the art controller the 8800 MT which offers a very high frequency resolution with an exceptional data acquisition rate providing the perfect control for your testing. The controller offers a very low gain setup time without jeopardizing the gain adjustment accuracy. Thanks to our Auto Tuning Feature.

Among our competitors, Instron is the only global materials testing supplier that designs and manufactures its own load cells. This ensures that Instron load cells meet the unique requirements of materials testing such as; high accuracy over a wide measurement range, high stiffness, resistance to offset loads, accurate alignment and excellent zero stability. During tests carried out on dynamic machines, elements of the system are subject to acceleration. As a result, in addition to the force applied to the specimen, the load cell also reads forces resulting from its own movement and the mass of the grips and fixtures attached to it. The accelerometer in a Dynacell™ is right at the heart of the load cell, directly on the load axis. This removes the risk of errors in the acceleration reading resulting from off center loading. This way, the accelerometer is on the load line eliminating both amplitude and phase errors and automatic set-up takes less than one minute.

Electropuls Dynamic Testing Range

Instron’s ElectroPuls is a line of high-performance, electrodynamic testing systems designed to perform a wide range of dynamic and static tests on materials and components.

Servohydraulic systems offer unmatched flexibility in their configuration. Each system can be readily customized with the appropriate servo valve, manifold, and hydraulic power unit, allowing laboratories to tailor the setup to the specific needs of their application. This adaptability ensures that the system’s performance matches the demands of each test, from low-force biomedical evaluations to high-force structural assessments.

• Servo Valves and Manifolds: Servo valves regulate the flow of hydraulic fluid, controlling the speed and force of the actuator. By selecting the right servo valve size, users can optimize their system for high precision or high-speed testing scenarios. Manifolds ensure the smooth distribution of hydraulic fluid, minimizing pressure drops and maintaining consistent performance.
• Hydraulic Power Units (HPUs): The HPU is the heart of any servohydraulic system, supplying the necessary hydraulic pressure to operate the system. HPUs can be configured to meet the specific requirements of the test setup, ensuring the system delivers the needed power without excessive energy consumption.
