Abstract

Aiming at the problems of traveling wave resonance (TWR), unclear stress distribution and vibration response characteristics of aviation high-speed thin-walled bevel gears, a transient dynamic simulation model of TWR of aviation high-speed bevel gears close to the actual meshing state, constraints and loads is established. The explicit dynamic algorithm is used to solve the model, and the effective characterization of the dynamic response characteristics of TWR of bevel gears is realized. The distribution state and spectral structure characteristics of the TWR displacement and stress response of the gear are accurately described. The distribution form and migration characteristics of the TWR stress field of the bevel gear are given for the first time. The validity and accuracy of the simulation model are verified by experiments. The results show that under the resonance conditions of the 3rd ND forward traveling wave (FTW) and the 4th ND backward traveling wave (BTW), the axial vibration displacement field of bevel gear is characterized by the rapid migration of sector distribution. The resonant stress field of the traveling wave shows a petal-like distribution in the circumferential direction, and the stress is concentrated at the center of the root groove fillet. The vibration displacement and stress response of the bevel gear TWR are characterized by the dense distribution of high-order harmonic vibration, and the vibration response at the meshing position is obviously increased, which is characterized by the obvious fluctuation phenomenon with the shaft rotation frequency as the cycle. By comparing the simulation results with the experimental results, it is found that the stress distribution characteristics of the two are consistent, and the magnitude of the results is consistent, which verifies the validity of the TWR transient dynamics simulation model of the bevel gear.

航空发动机高速薄壁锥齿轮行波共振精确表征及实验研究

针对航空高速薄壁锥齿轮行波共振（TWR）、应力分布和振动响应特性不清晰等问题，建立了接近实际啮合状态、约束条件和载荷的航空高速锥齿轮行波共振瞬态动力学仿真模型。采用显式动态算法对模型进行求解，实现了对锥齿轮TWR动态响应特性的有效表征。准确地描述了齿轮TWR位移和应力响应的分布状态和谱结构特征。首次给出了锥齿轮TWR应力场的分布形式和偏移特征。通过实验验证了仿真模型的有效性和准确性。结果表明：在第3 ND前向行波（FTW）和第4 ND后向行波（BTW）的共振条件下，锥齿轮轴向振动位移场呈现扇形分布快速迁移的特征；行波共振应力场在周向呈花瓣状分布，应力集中在根槽圆角中心。锥齿轮TWR的振动位移和应力响应具有高次谐波密集分布的特点，啮合位置的振动响应明显增大，且以轴的旋转频率为周期存在明显的波动现象。通过仿真结果与实验结果的比较，发现两者的应力分布特征一致，且结果的幅度一致，验证了所建立的锥齿轮TWR瞬态动力学仿真模型的有效性。

期刊介绍： Thin-walled structures comprises an important and growing proportion of engineering construction with areas of application becoming increasingly diverse, ranging from aircraft, bridges, ships and oil rigs to storage vessels, industrial buildings and warehouses. Many factors, including cost and weight economy, new materials and processes and the growth of powerful methods of analysis have contributed to this growth, and led to the need for a journal which concentrates specifically on structures in which problems arise due to the thinness of the walls. This field includes cold– formed sections, plate and shell structures, reinforced plastics structures and aluminium structures, and is of importance in many branches of engineering. The primary criterion for consideration of papers in Thin–Walled Structures is that they must be concerned with thin–walled structures or the basic problems inherent in thin–walled structures. Provided this criterion is satisfied no restriction is placed on the type of construction, material or field of application. Papers on theory, experiment, design, etc., are published and it is expected that many papers will contain aspects of all three.
