بازدیدکننده گرامی این صفحه در حال بروزرسانی و بازطراحی میباشد لذا ممکن است در حال حاضر برخی از مطالب قابل رویت نباشند
- Machine is designed as per ASTM E1942
- Operating mechanism: Servo Hydraulic Actuator
- High accuracy in applying dynamic loads with various amplitudes: constant force, constant displacement, constant stress, and constant strain according to types of fatigue wave patterns including sinusoidal, square, triangular, saw-tooth, and required form or random points pattern
- Capable of performing static tensile, compression, and cyclic tests
- Self-aligning compression grips can be installed for testing cylindrical specimens in order to report compression strength, longitudinal strain, lateral strain, and elastic modulus accurately by specialized extensometers
- Special bending grips can be installed to test concrete and steel beams; and calculate the bending modulus
- Applying fatigue loads with high frequencies for compression and bending tests
- Equipped with separate PID controllers for each controlling mode; defining the accurate wave pattern on the software
- Interface with DSP technology, working frequency 5 KHz, controlling and measuring the force, extension, and strain with 5 KHz frequency response (closed loop)
- Using state-of-the-art electronic components with quick response and high sampling rate, and good quality hydraulic servo valves
- Using accurate dynamic low profile load cell to reduce the effects of lateral forces
- Equipped with digital non-contact linear encoder installed on the jack (full stroke)
- A powerful software capable of real time controlling in different experiments, and processing the data
- Special oil seals in actuator for dynamic test and elevated temperature, bear in mind that all parts and measuring instruments and controllers should operate in long-term tests
- Equipped with four columns with high rigidity to dynamic loads
- Slotted bottom with certain dimensions for installing various compression and bending grips
- Equipped with hydraulic interlock system for clamping and crosshead lifting mechanism
- Stroke adjustability ensures performing various static tests
- Proper cooling system to increase the oil life
- A compensating system for errors caused by the machine stiffness and exerted inertial forces
Axial fatigue testing machines (SAF series) can perform fatigue and durability tests to determine the service life of various specimens according to different standards including ASTM E1924, ISO 14242, etc. They can apply dynamic loads with sinusoidal, triangular, square (with the capability of determining slope), saw-tooth, and random patterns, assuming the corresponding wave pattern within the range of force, extension, stress or strain. State-of-the-art electronic hardware with quick response and high data acquisition rate, good quality transducer, the most accurate servo valves, as well as real time individual controllers are used in this equipment. Powerful software with optimization algorithms, and data processing for each control mode, as well as special hydraulic/mechanical systems designed for long-term tests enable the fatigue machine to simulate and implement the most real and diverse circumstances for fatigue test of specimens. Operating mechanism of this equipment is by Hydraulic Servo Valves; DSP hardware with high frequency is used. Quick response, high data acquisition rate and control system enables the machine to get feedback from the measurement instruments per 200 microseconds (closed loop control with respect to PID controller). The fatigue machine is also capable of performing crack tests (crack initiation and crack growth tests). The machine has special and advanced software (Intranet connection with the hardware via LAN port) with the capability of applying periodic loads with specified amplitude and frequency but different wave patterns, applying noise, offset, quantity of applied cycles, and determining stored cycles. All test parameters can be changed online, during test and all the required outputs can be reported. The fatigue machine is equipped with water inter cooler system with new plate heat exchanger with high efficiency to dissipate the oil temperature.
