摘要

碳纤维增强复合材料具有高比强度、高比刚度和结构可设计性等优点，已成为轻量化工程应用的首选材料。以铝合金电气柜体为原型，设计了碳纤维复合材料电气柜体，进行了静强度计算和模态对比分析，并通过了冲击振动和防护等级试验验证。有限元分析和试验验证结果表明，碳纤维复合材料电气柜体能满足轨道车辆的运行要求，具有良好的轻量化效果，为今后碳纤维增强复合材料在轨道交通电气装备上的应用积累了经验。

Abstract

Carbon-fiber composite has become the preferred material for lightweight engineering applications, because of its high specific intensity, high specific stiffness, and good structural designability. With an aluminium alloy electric cabinet as the model prototype, a carbon-fiber composite cabinet was designed, and the contrastive FEA of static strength and modal was finished, which passed the shock and vibration and protection tests. According the results of FEA and tests, the carbon-fiber composite electric cabinet could meet the operation requirements for railway vehicles with good lightweight effect, which accumulated experience for the future application of carbon-fiber composites in the electrical equipment of railway transit.
