STUDY OF FREQUENCIES AND ACCELERATIONS PRESENT IN RAILROAD FREIGHT CARS

A series of tests was conducted to obtain data on vibratory conditions in a freight car and its effect on damage to lading. This type of data is helpful in establishing lading damage index and as a criterion for packaging against vibration. The tests indicated that the vibrations present in the freight cars can be divided into three groups: (a) Those, caused by excitation of the suspension system, (b) Those, caused by excitation of major structural members, (c) Noise and resonance of the structural components. The damaging effect is probably in the same order as mentioned above. It was definitely shown that the accelerations in the cars equipped with A.A.R. 1915 trucks are by far the largest.
