ANALOG-COMPUTER SIMULATIONS OF END IMPACT OF RAILWAY CARS

Description is given of attempts to simulate, on an analog computer, the impact of two railway cars. It is found that considering each car as a single lumped mass gives results nowhere near those measured from physical tests. Considering each car to consist of two lumps, structure and lading, allows reasonably accurate results to be obtained, as shown by various comparisons of simulated and physical results. The complication involved in making better representations of railway cars is discussed in relation to the problems of simulating the overall motions of trains.
