BODY ROLLING AS INFLUENCED BY BOGIE SUSPENSION--2

The effective length of the swing links should be considered in terms of the natural frequencies of lateral and nosing oscillations, as well as swaying, frequently, the use of relatively long links is desirable to reduce the sensitivity of the suspension to lateral track irregularities and to achieve a low natural frequency of the lateral track irregularities and to achieve a low natural frequency of the lateral and body nosing oscillations. Particular attention must be paid to lateral displacement for this is determined by the effective link length and the lateral force. Another solution consists of pre-loading the bolster laterally, the centering springs action increasing usually in direct proportion with the displacement, a feature found with leading bogies of steam locomotives and some modern bogie electric locomotives. The natural frequency of oscillation for a British Railways coach is determined mathematically. Articulated swing links used in Switzerland are briefly described.
