摘要
对某款乘用车的碳纤维复合材料防撞梁进行了研究。对碳纤维铺层进行了设计,通过有限元建模、施加边界条件与载荷,对碳纤维复合材料防撞梁的应力、变形与应力失效因数进行了分析,并对不同碳纤维铺层铺设角度进行了对比。通过设计与分析,使碳纤维复合材料防撞梁在满足要求的前提下,相比铝合金防撞梁质量减轻31.4%。
An anti-collision beam made of carbon fiber composite for a passenger car was studied.The carbon fiber layup was designed.The stress, deformation and stress failure factors of the anti-collision beam made of carbon fiber composite were analyzed by finite element modeling, application of boundary conditions and loads.The angles of different carbon fiber layups were compared.Through design and analysis, the carbon fiber composite beam could reduce its mass by 31.4% compared with the aluminum alloy beam provided that the requirements should be satisfied.
