摘要:基于轻量化原则,提出将碳纤维增强复合材料(CFRP)与钢材包裹套接的管式全地形车架设计方案。根据等刚度原则对全地形车架管件进行替代性设计,通过Hyper Laminate模块分析得出最优的碳纤维增强复合材料铺层方案,并分析钢/CFRP混合管件在静态载荷下的性能。为测试其抗弯刚度等性能,制作样件进行实物测试并进行相关模拟仿真。建立全地形车架三维模型及有限元模型,在多工况环境下对复合材料车架进行有限元分析,验证该方案满足相关设计要求。在多刚度自由尺寸优化后得到最终的钢/CFRP混合管式全地形车架设计方案,为研究复合材料在全地形车架中的应用起到了较好的借鉴作用。 
Abstract:Based on the lightweight principle, a tubular all-terrain vehicle composite frame program was proposed, combining carbon fiber reinforced composites (CFRP) with steel. The steel/CFRP hybrid pipe units, as the replacement of steel tube were designed according to the principle of equal stiffness, which performance was analyzed under static loading. At the same time, the optimal carbon fiber-reinforced composite layup design was sought through the Hyper Laminate module. In order to achieve the bending stiffness and other properties, samples were made for physical three-points bending test, and related simulation was performed. The three-dimensional model and finite element model of the hybrid tubular all-terrain vehicle frame were established to do the finite element analysis under multiple operating conditions, so that the programs can be proved to meet the relevant design requirements. After the multi-stiffness free size optimization, the final designs of the steel/CFRP hybrid tubular all-terrain vehicle frame were obtained, which is a good reference for studying the application of composite materials in the frame of all-terrain vehicles.
