Electronic measurement system of flexi-coil suspension springs test stand

The paper presented is dedicated to developing an electronic measurement system of test stand for evaluating the working condition of springs used in flexi-coil suspensions of railway rolling stock. The intended purpose of the system is to identify the characteristics of the spring being tested. The system identifies the vertical and horizontal load and displacement of the mounting domes of the springs, all measured by means of sensors [1]. After the measurement steps have been completed, the system outputs the identified characteristics for vertical and horizontal loading and gives a conclusion about the condition of the spring.
