Abstract The authors suggest that the strength of passenger car bodies under train ferry transportation can be provided by mounting fastening elements of chain binders on the body bolster beams. The principle of such an element is based on the hydraulic damper operation Therefore, the authors developed a mathematical model which considered displacements of a train ferry loaded with passenger cars under rolling motion. The model was solved in Mathcad software. The mathematic modeling was conducted in order to determine the dynamic loading on a passenger car body under sea transportation. The study established that the improvements mentioned made it possible to reduce the dynamic loading on the body under sea transportation by 30% in comparison with that of a typical fastening scheme. The strength of an improved passenger car body was calculated. The maximum equivalent stresses in the body structure accounted for about 120 MPa, i.e., they did not exceed the admissible values. Besides, the study presents the computer modelling of dynamic loads of the carrying structure of a passenger car body under train ferry transportation. Numerical values of the accelerations and their distribution fields relative to the carrying structure of a car were determined. The adequacy of the designed models was checked with an F-test. The research and proposed engineering solutions can ensure the adequate strength of passenger car bodies under their transportation by train ferries, and also conduct efficient international rail/ferry transportation.

客车车身改进提高列车渡轮稳定性

摘要 提出在列车轮渡运输中客车车身的强度可以通过在车体垫梁上安装链条捆绑件的紧固元件来提供。这种元件的原理是基于液压阻尼器的操作。因此，作者开发了一个数学模型，该模型考虑了装载客车的火车渡轮在滚动运动下的位移。该模型是在 Mathcad 软件中求解的。进行数学建模是为了确定海上运输下客车车身的动态载荷。研究表明，与典型的紧固方案相比，上述改进可以将海上运输中车身的动态载荷降低 30%。计算了改进后的客车车身的强度。车身结构中的最大等效应力约为 120 MPa，即未超过允许值。此外，该研究还介绍了火车轮渡运输下客车车身承载结构的动态载荷的计算机建模。确定了加速度的数值及其相对于汽车承载结构的分布场。通过 F 检验检查设计模型的充分性。研究和提出的工程解决方案可以确保通过火车渡轮运输的客车车身具有足够的强度，也可以进行高效的国际铁路/渡轮运输。该研究介绍了在火车轮渡运输下客车车身承载结构的动态载荷的计算机建模。确定了加速度的数值及其相对于汽车承载结构的分布场。通过 F 检验检查设计模型的充分性。研究和提出的工程解决方案可以确保通过火车渡轮运输的客车车身具有足够的强度，也可以进行高效的国际铁路/渡轮运输。该研究介绍了在火车轮渡运输下客车车身承载结构的动态载荷的计算机建模。确定了加速度的数值及其相对于汽车承载结构的分布场。通过 F 检验检查设计模型的充分性。研究和提出的工程解决方案可以确保通过火车渡轮运输的客车车身具有足够的强度，也可以进行高效的国际铁路/渡轮运输。通过 F 检验检查设计模型的充分性。研究和提出的工程解决方案可以确保通过火车渡轮运输的客车车身具有足够的强度，也可以进行高效的国际铁路/渡轮运输。通过 F 检验检查设计模型的充分性。研究和提出的工程解决方案可以确保通过火车渡轮运输的客车车身具有足够的强度，也可以进行高效的国际铁路/渡轮运输。
