大型公共运输中的热塑性组合框架结构的设计、制造和分析

薄壁复合材料具有优越的性能，包括高强度、轻质、抗弯、抗剪性强等，因而经常用于大型交通领域。从目前的研究来看，已经设计、分析并制造出一种用于大型运输卡车的薄壁复合热塑组合结构来代替传统的金属结构。考虑了三种横截面构造，分别是矩形、V字形、C形，对比了编织方向在（0／90）6，±45／（0／90）2]，及±45／（0／90）]3等不同的复合材料层合结构。该结构选用碳纤／聚亚苯硫化物（carbon／PPS）作为原材料，采用单模复合成型。通过面内冲压试验，验证了碳／PPS组合结构有限元分析结果，论证了薄壁碳／PPS热组合结构制造策略的设计理念。

Design, Manufacture and Analysis of a Thermoplastic Composite Frame Structure for Mass Transit

Thin-walled composite sub-elements possess excellent properties, including high specific strength, lightweight, internal torque and moment resistance which offer opportunities for applications in mass transit and ground transportation. In the present work, an open section thin-walled thermoplastic composite frame segment (sub-element) of a mass transit bus was designed, analyzed and manufactured to replace a conventional metal-based design. Three cross-section configurations, rectangular, V-shape and rounde...
