Open publisher page 0 citations

Abstract

Study of vehicle vibrations due to track defects is one way of assessing running safety and comfort and the stresses exerted on the various vehicle parts. The author considers the problem theoretically using a basis of mathematical statistics and the calculation of probabilities. From comparison of the results obtained with the experiments carried out using a 4-axle vehicle of the Y/B70 type, estimates have proved correct.
