The aim of this work is to show how the use of a composite body affects the behaviour of hybrid metal-composite gears during meshing. The proposed model compares a spur hybrid gear to a steel lightweight gear of equal mass in order to study the influence of the composite web on the mesh stiffness. In a finite element (FE) simulation environment, the body of the gear is represented as a sequence of CFRP unidirectional (UD) plies arranged in a symmetric layup and resulting in quasi-isotropic properties. Static non-linear FE analyses are conducted to evaluate the static transmission error (STE) curve of the hybrid gear pair and to compare it against the one achieved by a pair of steel gears with a thin-rimmed lightweight design and with the same macro-geometry properties. Additionally, a cohesive modelling technique is used to take account for the damage at the metal-composite interface.

这项工作的目的是展示复合体的使用如何在啮合过程中影响混合金属复合齿轮的性能。所提出的模型将直齿混合齿轮与等质量的钢轻型齿轮进行了比较，以研究复合材料幅材对网眼刚度的影响。在有限元（FE）仿真环境中，齿轮的主体表示为以对称叠层形式排列的CFRP单向（UD）层的序列，并产生了准各向同性的特性。进行了静态非线性有限元分析，以评估混合齿轮对的静态传递误差（STE）曲线，并将其与一对采用薄轮辋轻型设计且具有相同宏指令的钢制齿轮所实现的曲线进行比较。几何属性。另外，
