INSTRUMENTATION FACILITIES FOR DYNAMIC TESTING OF RAILWAY ROLLING STOCK

A wide variety of instrumentation facilities are used for dynamic testing of railroad rolling stock. For evaluating stability, measurements of the lateral force and vertical load on the wheel are required. The former is measured with the help of a load cell and the latter by measuring spring deflections using a linear variable differential transformer. For determining riding quality the average ride index is calculated and acceleration is measured using a seismic accelerometer. A transducer system is used to convert the physical parameters to electrical signals. As the electrical signals generated by the transducer are in the range of microvolts they are amplified by amplifiers which feed the signal to the recorder where the signals actuate pens, which trace out the signals in ink on paper.
