RAILWAY DYNAMIC TESTS

The verification of running safety and the quantitative assessment of the comfort of railway vehicles involves the taking of many dynamic measurements. The author first lists the range of the main recordings required and explains how they are taken: fitting of gauges, isolation of the phenomenon to be studied and transformation of the results into readings that can be interpreted more easily (usually an electric process), amplification, filtering, remote transmission of this data, reception and recording. The complex behaviour of a moving vehicle means that numerous phenomena must be recorded simultaneously and continuously by a whole series of measuring instruments. The author describes and explains in three sections the techniques used for measuring stresses and wheel-rail interaction, the series of measuring instruments, and the interpretation of the many and varied experimental results obtained, particularly with the TGV 001 trainset and the Z 7001 railcar. These results are very close to those obtained by calculation; they show the high value of the method using an analogue computer.
