摘要

可持续发展的概念优先考虑能源效率，特别是在运输方面，这直接影响到环境的可持续性。本研究首次通过将实验道路数据与有限元（FE）验证相结合的混合方法，展示了一辆25米、三段、双铰接的客车车身框架的轻量化设计和结构性能。建立了有限元模型，并在各种条件下进行了分析。轻量化研究使用拓扑优化、设计修改和不同的材料进行。收集真实路况数据并与模拟结果进行比较，在特定点实现了高达93%的相关性。因此，在不影响安全性或乘客容量的情况下，客车车身框架的重量减轻了14.1%。这种轻量化通过减少车辆使用寿命期间的排放，为可持续交通做出了重大贡献。

Lightweight design and structural analysis of a Bi-articulated bus: Experimental measurements and FEM validation

The concept of sustainability prioritizes energy efficiency, especially in transportation, which directly impacts environmental sustainability. This study presents, for the first time, the lightweight design and structural performance of a 25-meter, three-section, double-articulated bus body frame through a hybrid methodology that integrates experimental road data with finite element (FE) validation. A finite element model was created and analyzed under various conditions. Lightweighting studies were performed using topology optimization, design modifications, and different materials. Data from real road conditions were collected and compared with simulation results, achieving up to 93% correlation at specific points. As a result, a 14.1% weight reduction was achieved in the bus body frame without compromising safety or passenger capacity. This lightweighting contributes significantly to sustainable transportation by reducing emissions over the vehicle’s lifetime.
