TRANSMISSION OF VIBRATIONS BY SUSPENSION ELEMENTS AND CONNECTION COMPONENTS WITH THE VEHICLE BODY. THEORETICAL INVESTIGATION OF COACH-BODY VIBRATIONS

The dynamic phenomena arising in the contact area between rail and wheel are transmitted to the body through the bogies via their suspension and damping systems. The present report deals with the theoretical investigation of coach-body vibrations, for the following cases: in-phase excitations due to out-of-roundness on the 4 axles; excitations of opposed phase due to out-of-roundness on the 4 axles; excitations due to out-of-balance on the 4 axles. The influence of the various parameters on the transmission of vibrations could in this way be evaluated. In the general conclusions, a comparison is made between the theoretical investigations and the results of the tests on the test-rig.
