Abstract
2017 marks the 100th anniversary of the birth of Oleg Petrovich Ershkov - one of the leading scientists of VNIIZhT (currently JSC “VNIIZhT”), Doctor of Technical Sciences. All his scientific work was devoted to the problems of the interaction of rolling stock and the track in curves. The generalized analytical method developed by him to determine the transverse forces in curves and the graphs of the lateral effect of locomotives on the track constructed by this method made it possible to find the values of these forces practically at any radius of the curves, the elevations of the outer rail and the speeds of motion. And today the direction of the scientific activity of O. P. Ershkov is in demand taking into account changing operating conditions. On the basis of experimental studies and generalization of foreign experience, Cand. Tech. Sci. V. Ya. Kartsev was able to determine, under the conditions of traffic safety and comfortable driving of passengers, the propagation to a speed of 250 km/h of the rate of increment of the unprecedented acceleration of 0.6 m/s3 and an increase in the rate of lifting of the wheel along the elevation to 50 mm/s. The new “Guidelines for determining the elevation of the outer rail and the speed of movement in curves” was approved. O. P. Ershkov is the author of more than 100 publications. At the present time, the order of the structure of curves is being developed taking into account the specialization of the lines. The modern generation of scientists and young researchers of VNIIZhT, based on the experience and knowledge of the older generation, adequately continues the scientific traditions of VNIIZhT in this field of knowledge.
