Функциональные испытания перспективного вагона-цистерны для перевозки расплавленной серы модели 15-9544

Abstract

В статье описаны конструкторские решения, реализованные в перспективном вагоне-цистерне модели 15-9544, а также функциональные испытания опытного образца данного вагона. По результатам испытаний сделано заключение, что устройства загрузки-разгрузки, системы теплоизоляции и электроразогрева соответствуют требованиям технического задания, а примененные в ходе проектирования вагона разработки дали положительный эффект.

The article contains analysis of the experience and the results of the test center of rail car-building products. It describes design solutions, implemented to construction of the prospective tank car model 15-9544, and functional testing of its prototype. In particular, the main structural difference of experimental rail car sample related to functional testing, compared to similar type of car is an annular gap between the wall of the boiler casing and the shell in the upper part of the rail car. An insulation made of thin basalt fiber is used as well. Insulation casing with bottom parts made of composite materials and heating system is equipped with heat screens. In the upper part of the rail car insulation layer of the car is increased by 15%. Loading and unloading devices of the test rail car also have features. As concerns the results of the functional test, impairments of structural elements of the rail-car and loading and unloading terminals haven’t been identified. Loading and unloading devices, systems and insulation electrowarming are functional and confirm performance declared in the technical documentation. Thus, according to the results of functional tests, the loading and unloading devices, insulation and electrowarming systems meet the technical specifications. Furthermore the modifications the rail car had distinctive positive effect.
