The recent increases in passenger train operating speeds have necessitated the development of passenger car spring suspension systems which provide riding comfort at high speed. Much of the development of these high speed passenger car trucks was based on test results and the interpretation of test data. However simplified mechanical system of a passenger car were considered and analysis by the mathematical theory of mechanical vibrations provided the only means whereby results could be predicted. The principles governing the vibration of masses supported by simple spring suspension systems are given in texts on vibration listed in the bibliography of this thesis. This thesis has been written to present the mathematical development of the principles of vibration of spring suspended masses in a manner which facilitates analysis of rail vehicle suspension problems. The application of mathematical analysis to study the characteristics of a widely used ride recording instrument is included and a chapter correlating the theoretical analysis with actual test observations and data is also given.
