Abstract

The article discusses methods to enhance the technical and operational characteristics of railway carriages through innovative design solutions. It primarily focuses on reducing the weight of the railway carriage by modifying the supporting floor, which improves energy efficiency and performance. Mathematical modeling and strength calculations have demonstrated that the modified supporting floor can significantly reduce maximum equivalent stresses, thereby ensuring the reliability and safety of the structure. Dynamic modeling has confirmed that the new design meets regulatory standards for stability and safety at various speeds. A comparative analysis with existing models of railway carriages shows that the new design can reduce weight by 1.4-5.4%, leading to substantial improvements in energy efficiency and lower operating costs. The results highlight the significance of optimizing railway carriage design to achieve enhanced strength, safety, and economic efficiency in railway transport.

摘要

本文讨论了通过创新设计解决方案来提升铁路车厢技术和运行特性的方法。它主要聚焦于通过改进支撑地板来减轻铁路车厢的重量，这提高了能源效率和性能。数学建模和强度计算表明，改进后的支撑地板可显著降低最大等效应力，从而确保结构的可靠性和安全性。动态建模证实，新设计在各种速度下均符合稳定性和安全的监管标准。与现有铁路车厢模型的对比分析表明，新设计可减轻重量1.4 - 5.4%，从而大幅提高能源效率并降低运营成本。结果凸显了优化铁路车厢设计对于在铁路运输中实现更高强度、安全性和经济效益的重要性。
