Показано, что при изменении скорости движения необходимо менять состав слагаемых случайного процесса геометрических неровностей рельсового пути. Определены требования к параметрам вероятностного анализа, приведены примеры генерации и результаты спектрального анализа случайных неровностей для различных скоростей движения.</p></abstract><trans-abstract xml:lang="en"><p>Previous works contained correlation and spectral  analysis of the four-dimensional  disturbance  process in the form of vertical and horizontal irregularities of left and right rails, causing oscillations in rail vehicles. But when speed increases, the disturbance frequency range shifts to high frequencies and can go beyond natural frequencies of the system. Then disturbance almost ceases to excite a part of vibration frequencies and obtained results will be incorrect.</p><p>The article considers requirements to the procedure of computer generating a multidimensional stationary random disturbance process, causing vibrations of rail vehicles.  Using  modeling,  computer  simulation,  and mathematical analysis it is shown that when the speed alters it is necessary to change terms of the composition of the random process of geometrical irregularities of the  track.  The  requirements  for  parameters  of  the probabilistic analysis are determined, examples of generating and the results of spectral analysis of irregularities generated for different speeds are shown.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рельсовый экипаж</kwd><kwd>случайные процессы геометрической неровности рельсового пути</kwd><kwd>слагаемые аналитического выражения</kwd><kwd>влияние скорости движения</kwd><kwd>спектральный анализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rail vehicle</kwd><kwd>random processes of geometric irregularities of the track</kwd><kwd>terms of an analytical expression</kwd><kwd>impact of speed</kwd><kwd>spectral analysis</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ромен Ю.
