![]() ![]() ![]() The processing power of the vibration and control computer is provided by 36 digital signal processors operating in parallel which interface with the operator through several PCs. It is based on online test value calculations for the control signal of the servo valves, taking the geometrical arrangement of the servo actuators and the test table into consideration. At frequencies above 20 hertz accelerations of up to 5g have been achieved.Įngineers designed and developed the vibration and control computer subsystem for HYDRA. The test envelope that can be covered by HYDRA covers acceleration ranges from 20 milli-g to 3g in the frequency band 1-100 hertz. This allows engineers to test specimens along both the vertical and lateral axis with a single test set-up. HYDRA is unique in being able to perform mechanical vibration tests at frequencies between 1-100 hertz in all axes of motion (translation and rotation) simultaneously. What are its features?
