DEVELOPMENT OF A RAILROAD ROUGHNESS INDEXING AND SIMULATION PROCEDURE

To simulate rail vehicle performance on an analog computer to study shock and vibration characteristics of various rail and cargo configurations, input must be provided representing the roughness characteristic of the rail surface. Methods for measuring and simulating rail surface roughness are described which resulted in a recommendation to use a white noise generator to provide the required inputs. Measured accelerations on cargo were found to approximate the characteristics of white noise.
