STM-100 includes all software and hardware capabilities of the STM series. Modifications and added accessories enable long-term high-temperature and creep rupture testing. The operating mechanism is servo-mechanical with ball screws, driven by an AC servo motor and driver a very low-speed operation. Force is measured by a low-profile 10-ton load cell, accuracy class 0.5 (max. error 0.5% of the reading within 2% to 100% of load cell capacity) in compliance with ISO 7500 and EN 10002 ensuring precise stress control. The system is equipped with a circular furnace featuring three dedicated heating zones for uniform vertical and angular temperature distribution, enabling the application of thermal stress during long-term tests. The furnace operates at max. temperature up to 1100 ˚C, and each zone is individually controlled through a digital controller through and HMI touch-screen panel (three-zone PID controller). The system supports three thermocouples for measuring the mean specimen temperature and the furnace bulk temperature, with automatic compensation for temperature gradients between zones based on real-time specimen thermocouple feedback, with a resolution of 0.1˚C. The furnace can move vertically relative to the specimen for easy access and adjustment of both the specimen and thermocouples. it can also be easily detached from the machine using supporting arms and guide rods. Various jaws can be fastened to hydraulic interface for clamping round threaded specimens (M4, M6, M8, M10, M14, M16) as well as flat samples, in accordance with DIN 50125 Type B and/or ASTM E8 (sub-size). The jaws are made of superalloy and are suitable for use at temperature up to 980 ˚C. The machine features displacement sensor without restriction, providing 0.1 µm resolution in no load mode and displacement measurement accuracy better than 0.05 mm at full stroke. it also includes a specialized extensometer attached to the specimen inside the furnace, measuring strain with 0.001 mm accuracy. The stroke of the machine is designed to accommodate the load cell, grips, and in-furnace interfaces. The system is equipped with a hydraulic unit and auxiliary devices, selected according to the required linear speed and specified flow rate. These components are essential for accurately determining the machine’s linear speed, testing frequency, and displacement. The machine is capable of performing fatigue and durability tests, as well as determining the service life of various specimens in compliance with international standards, including ASTM E1942 and ISO 14242. It can apply dynamic loads in multiple patterns such as sinusoidal, triangular, square, and saw-tooth with the additional capability of defining random tests based on the wave patterns. Furthermore, the system supports Spectrum Tests within the specified range of force, extension, stress, and strain, at frequencies of up to 100 Hz. The equipment integrates advanced electronic hardware with high response speed and data acquisition rate, precision sensors and transducers, servo-hydraulic valves, and a dedicated real-time controller. An enhanced software with upgraded algorithms ensures accurate data processing across all control modes. Together with the robust hydraulic and mechanical design for long-term operation, the SAF series fatigue testing machines are capable of simulating real-world fatigue conditions for a wide variety of specimens. The operating mechanism is servo-hydraulic, utilizing a high-performance hydraulic servo valve and DSP-based technology for high-frequency operation. The machine features a high-frequency response and a sampling rate of 5000 samples per second (one sample every 200 µs), enabling accurate measurement, rapid feedback and precise closed-loop control via the PID controller. In addition to common fatigue tests, the SAF-10B can also perform crack initiation and crack growth tests, as well as static tests. The enhanced software (with Intranet connection via LAN port) provides the capability to apply periodic loads with specified amplitude and frequency in various wave patterns, with additional such as adding noise, applying offset, defining the number of applied cycles, and recording saved cycles. It allows modification of all test parameters online during testing and generates comprehensive outcome reports. To extend the service life of machine components, a water-cooling system with a plate heat exchanger is integrated, ensuring efficient oil cooling. Equipped with lateral jacks and hydraulic locking system for crosshead displacement, controlled via the software menu for operator convenience.
