摘要：To ensure the strength of the passenger car bodies during transportation on train ferries,it is proposed to mount fastening elements of chain binders on the body bolster beams. The principle ofsuch an element is based on the hydraulic damper operation. The mathematic modelling was conductedin order to determine the dynamic loading on a passenger car body during sea transportation. Thestudy established that the improvements mentioned made it possible to reduce the dynamic loading onthe body during sea transportation by 30 % in a comparison with that of a typical fastening scheme.The strength of an improved passenger car body was calculated. The maximum equivalent stresses inthe body structure accounted for about 120 MPa, i.e., they did not exceed the admissible values. Theconducted research may contribute to ensuring the required strength of passenger car bodies duringtrain ferry transportation, thus leading to a higher operational efficiency of train ferry transportationwithin the international transportation.
