Refinement of Forces Acting on Car Bodies in the Course of Their Transportation by Ferry-Boats
There are represented the results of investigations tackling special features of car bodies' interaction with security arrangements fixing them relative to the railway ferry-boat decks. There were found main drawbacks of standard car body fixing patterns traditional for international rail-water traffic services. There was also examined force impact on those car body structural elements, which are employed by fixing provisions, exercised under various sea-state and hydrometeorological conditions of the aquatic area where ferry-boats are operated. There were analyzed forces affecting strength characteristics of the car body supporting members and ferry-boat deck relative stability coefficient of railway car. There were conducted dynamic studies of a freight car body operated in international rail-water services under sea disturbance conditions with respect for variety of railway ferry-boat hull relative wave obliquity values. There were examined most essential freight car vibration motion patterns under the sea disturbance conditions affecting its stability as relative to the ferry-boat deck. There were carried out supporting members' strain-stress state calculations of car bodies transported by railway ferry-boats under sea disturbance conditions. Practical application of the calculated data will contribute to better strength, reliability and integrity of railway rolling stock operated in international rail-water services as well as to more reliable delivery of international cargo.
