بازدیدکننده گرامی این صفحه در حال بروزرسانی و بازطراحی میباشد لذا ممکن است در حال حاضر برخی از مطالب قابل رویت نباشند
- Design according to ASTM E1942
- Accessories designed according to asphalt testing standards ASTM, EN, BS, AS, and ASTM
- Servo hydraulic operating mechanism
- Capable of mounting 20 types of accessories for specialized asphalt tests such as: compressive, dynamic modulus study (hot mix), semi-circular bend, indirect tensile, DSCT test, overlay test, creep testing, Hoek triaxial test, 4-point bend fatigue and cyclic tests under controlled loads
- Hot and cold chamber in various temperature ranges with temperature control at ambient temperature (20ºC)
- High precision in applying dynamic and controlled loads with various amplitude of constant force, constant displacement, constant stress, and constant strain according to different types of fatigue waveforms: sinusoidal, square, triangular, saw-tooth, as well as arbitrary or random points patterns
- Furnace with PT100 thermocouples and PLC control, as well as programmable HMI display
- Applying high frequency fatigue loads at both ambient and furnace conditions
- Equipped with individual PID control system for each control condition as well as applying accurate waveform defined in the software
- Interface with DSP technology, 5KHZ working frequency; load, displacement and strain measurement and control by means of extensometer (closed loop method)
- Low profile dynamic load cell for reduction of lateral forces effects
- Digital non-contact linear encoder mounted on jack for the whole stroke
- Powerful software with Real Time control in all tests as well as processing them
- MOOG servo valve (USA made)
- Appropriate intercooler system
SAF axial fatigue test machine can carry out fatigue and durability tests on different samples according to standards and instructions including ISO 14242, ASTM E1942, etc. It is also used to apply dynamic loads with 4 standard patterns, capable of defining combined patterns or assuming wave pattern in force, displacement, stress and strain amplitudes up to 50 Hz. Using the latest electronic hardware with fast response and quick sampling, best sensors and transducers with most accurate servo valves as well as application of separate real time controller, powerful software with enhanced algorithm and data processing for each control conditions and designing unique hydraulic and mechanical systems for long term tests enable the fatigue test machine to simulate and perform the most real and diverse conditions for fatigue test on asphalt. The unit has a non-contact digital sensor on the Actuator with no limitations in the stroke, 1µm resolution, and accuracy 0.05mm through the whole stroke. The machine jack is bidirectional (bidirectional actuator) with constant pressurized surfaces. Its operating mechanism is hydraulic servo valve and can be supplied with different linear speed and measuring units. The hardware is of high frequency DSP technology. The machine has very high frequency response and sampling rate so that every 200 microsecond, the machine receives feedbacks from the measuring instruments and controls in closed loop with PID control system. Moreover, SAF-100 can perform crack tests (initiation and growth) as well as usual fatigue tests. The machine chamber is designed to carry out hot and cold tests. For hot test there is a heater that increases the temperature up to 80˚C (long term) but in cold test reduces the temperature to -50˚C. The control system is of PLC type with PT100 thermocouples with HMI display. The temperature resolution is 0.1˚C and heat uniformity in the furnace does not exceed ±0.5˚C. There is also a special and advanced software in the machine (Intranet connection via LAN port to the machine hardware) capable of applying periodic loads with specific amplitude and frequency and different waveforms, applying noise, offsetting and number of applied cycles as well as determining the restored cycles. There is also the possibility of changing all test parameters online and reporting all the required outputs. The cooling system is water-cooled intercooler with a new plate heat exchanger and high efficiency in dissipating oil temperature in the machine.
