Electronic measurement and registration system of hydraulic dampers test stand

The paper presented is dedicated to developing an electronic measurement and registration system of hydraulic dampers test stand and equipment for the needs of Sofia Metropolitan. The intended purpose of the system is to evaluate the working condition of hydraulic dampers of oscillations by identifying their characteristics with certain accuracy. For that reason the electronic system of the test stand identifies the resistance force and relative displacement of the mounting devices of the damper, all measured by means of sensors [1], outputs the identified characteristics and gives a conclusion about the working condition of the damper.
