KEY DEVELOPMENT FACTORS OF THE TRANSIT AND TRANSPORT POTENTIAL OF KAZAKHSTAN

Summary. Nowadays, the Republic of Kazakhstan is dynamically forming up its transit policy, improving its directions and the development of new vectors. This article looks into the development of the transit and transport potential of the Republic of Kazakhstan. It presents the main conclusions on the development of a feasibility study for the construction of a logistics terminal in the seaport of Lianyungang (China) as one of the directions of building transit policy, improving its direction and the formation of new vectors. The urgency of building a logistics terminal is conditioned by the necessity for national interests and further expansion of political and economic advantages of Kazakhstan

THE DETERMINATION OF ADMISSIBLE SPEED OF LOCOMOTIVES ON THE RAILWAY TRACKS OF THE REPUBLIC OF KAZAKHSTAN

Today modern locomotives of KZ4AС, KZ8A, ТE33А series were put into service in the Republic of Kazakhstan. In order to establish safe operating mode of these locomotives the admissible speed on the railway tracks of the Republic of Kazakhstan was determined. The admissible speed of locomotives was determined on the basis of analysis on the results of dynamic and railroad tests and calculations for stress of railway construction

Simulation of dynamic processes of interaction of car and railway track during train passage of curved sections of the track

In this article, the considered principles for the development of calculation schemes and the subsequent formation of vibration equations are a special case of classical simulation of motion in space of solid body systems connected in space by kinematic connections. This approach is useful with limited computational capabilities and an assumption of the relatively small body movements inherent in railway crew bodies, and reduces the task of motion research to analysis of fluctuations. Various design schemes of freight car truck, mathematical modeling of systems dynamics, "crew-track" safety of freight car movement and withdrawal under different technical conditions of running parts and track are considered in this work

OPTIMUM DISTRIBUTION OF REPAIRS IN ТS-8 OF ELECTRIC LOCOMOTIVES VL80С BETWEEN REPAIR DEPOTS IN THE REPUBLIC OF KAZAKHSTAN

The article presents the solution for the problem of optimal distribution of electric locomotives in repair enterprises for carrying out repairs in the frame of technical service - 8 (ТS-8) and increased technical service - 8 (ITS-8). The aim of the study is to improve the efficacy of a rolling stock with a simultaneous decrease in the total expenses connected with the repair of locomotives and their transportation in repair enterprises. This is possible due to a reduction in the requirement for repairs by optimization of a resource before change of wheel bandages in electric locomotives VL80С that promotes an increase in their between-repairs run
