SOME ASPECTS OF THE THEORY AND PRACTICE OF DAMPING--II

When mounting dampers across the secondary suspension of a vehicle body pitching and swaying oscillations must be accounted for. The lateral motion on the swinglinks can be damped without difficulty, however, rolling on the bolster springs is difficult to damp with hydraulic units since the frequency of the oscillations is often low (about 0.5 to 0.8 c/s) and the moment arm short. Resonance conditions in the swaying mode must if at all possible be avoided at the operationally important speeds since control by hydraulic damping is unlikely to prove an acceptable solution.
