LATERAL RAIL IRREGULARITIES -- MEASUREMENT AND APPLICATION

Railway vehicles are excited to vibrations by various effects. One of these effects which presents an important source of excitation, are the lateral rail irregularities. High safety and comfort require small irregularities and a high quality suspension system. This quality depends on a lot of different vehicle data. To acquire these data, experiments and field tests are unsuitable. Computer simulation can yield results during the design period, provided that the simulation model is representative enough and that the rail irregularities are known. This paper presents a mathematical model for the simulation of lateral railway dynamics, caused by lateral rail irregularities. The chosen model represents a two-axled wagon running on rails which allow a lateral displacement. The rail irregularities are defined, the measurement is explained and the results are discussed. The ride behavior is then simulated and compared with the corresponding measurements.
