Actuators JAF series are mainly intended to study a structure (or a machine) performance and real lifetime against applied alternating forces to determine the conformity to their design and lifetime calculations. These actuators are used to apply dynamic loads with sinusoidal, triangular, rectangular (with the capability of determining the slope), saw-toothed, and random patterns, by assuming the wave patterns within the range of force and displacement up to 100 Hz according to servo valve diagram. Using state-of-the-art electronic hardware with fast response and data acquisition rate, qualified sensors and transducers, as well as the most accurate servo valves, individual controllers for real time control, powerful software with optimized control algorithm and data processing for every control mode; hydraulic/mechanical system design especially for long-term tests enable JAF actuators to provide the most real and diverse conditions to test the service life and durability of structures and different simulating equipment practically. The mechanism and function of this type of machines are hydraulic servo valve using hardware system with high frequency DSP technology. Frequency response, sampling rate and system control speed is so high in this unit that each 200 micro seconds it gets feedbacks from all measuring instruments and controls system via closed loop regarding the PID. Moreover, JAF-50 in addition to carrying out dynamic tests can perform static loading. The unit has special and advanced software (Ethernet connection with hardware via LAN port) with the capability of applying periodic loads with certain amplitude and frequency, different waveforms, noise exertion, offset, number of applied cycles and determining restoring cycles, the ability to change all test parameters online while testing and report all required outputs. JAF-50 has a water intercooler (cooling system) with new plate heat exchanger and high efficiency for oil heat dissipation.
