The researching of the dynamic properties of long-wheelbase platforms for the transportation of large-capacity containers

Abstract

The modern market of transport services requires the saturation of the car fleet, a specialized type of construction designed to carry a special kind of cargo, for example, heavy cargo containers, various automotive equipment, etc. It is necessary to increase the speed of movement and safety of the goods carried. A review of the work related to the improvement of the running parts of freight cars showed that over the past 50 years a large number of different types of freight wagon carriages have been developed. At the same time, the main attention was paid to the improvement of individual elements during the creation of bogies, and the problem of the wear of the part of the trolleys was solved while preserving the unchanged ideologues lay in the CRI-Х3 trolley. However, the question of the choice of constructive schemes and rational parameters of the spring suspension of bogies is not completely resolved.

Research of the operation of the turnstile support-fastening device during the transportation of a long-dimensional heavy load

“…When testing for impact, the coupler performs complex spatial vibrations due to the work of draft gears and spring suspension of the car, as well as the turnstile support and fastening device [2]. An analytical study of these oscillations in the most complete and general form leads to the need to compose and solve a system with a large number of differential equations [3]. The interdependence between numerous design parameters is complex, so it is almost impossible to accurately assess the effect of one or another parameter on the dynamic qualities of cars.…”
