摘要: 本文将碳纤维增强复合材料(CFRP)引入重卡板簧的设计之中,提出一种CFRP多片簧结构。利用有限元仿真分析对CFRP多片簧的强度和刚度进行协调匹配设计,得出CFRP单片板簧的铺层角度为[033/±75]5,并通过台架试验对仿真模型进行优化,利用ABAQUS软件建立优化后的有限元仿真模型,并通过CAE对CFRP多片簧在工作载荷、极限载荷和疲劳加载等工况下进行可靠性分析,预测CFRP多片簧的刚度和疲劳寿命,对CFRP多片簧试验件进行台架试验。结果表明,CFRP多片簧的质量为34.4 kg,减重45%以上,经历15万次的循环加载后,CFRP多片簧的刚度并未下降,且仍能承受20 t的载荷而不破坏。

Abstract: This paper introduces carbon fiber reinforced plastic (CFRP) into the design of heavy truck leaf springs and propose a CFRP multi-leaf spring structure. Using finite element simulation analysis to coordinate and match the strength and stiffness of CFRP multi-leaf springs, which yields a lay-up angle of [033/±75]5 for the CFRP single leaf spring, and optimize the simulation model by bench test, used ABAQUS software to establish the optimized finite element simulation model and CAE to predict the stiffness and fatigue life of CFRP multi-leaf springs under the conditions of working load, ultimate load and fatigue loading, and carry out reliability analysis of CFRP multi-leaf springs. Reliability analysis is carried out to predict the stiffness and fatigue life of CFRP multi-leaf springs, and bench tests are carried out on CFRP multi-leaf spring test pieces. The results show that the mass of the CFRP multi-leaf spring is 34.4 kg, achieving a weight reduction of over 45%. Additionally, the stiffness of the CFRP multi-leaf spring does not decrease after 150 000 cycles of cyclic loading, and it can still withstand a load of 20 tons without damage.

Key words: CFRP, leaf spring, finite element simulation analysis, bench test
