| 目的 发动机风扇盘组的装配质量直接影响发动机的可靠性和安全性，目前风扇盘组采用传统压入式装配，导致风扇盘组接触面间的摩擦力过大，磨损程度严重，影响其装配效率与装配质量。为解决上述问题，本研究采用超声振动辅助压装技术，探究其对风扇盘组高应力装配过程中接触面间摩擦力与磨损程度的影响。方法 首先建立了接触滑动数学模型以及微凸体磨损模型，其次对基于模拟风扇盘组结构的试验组件进行超声压装试验，观测不同超声振幅下组件接触面间的摩擦力以及磨损程度。结果 与超声振幅为0 μm时相比，超声振幅为15、28、41、58 μm时，组件接触面间的摩擦力分别降低21.9%、22.6%、41.1%、58.9%。当超声振幅为0 μm时，接触面上有明显的连结成片的黏着磨损，磨痕表面有宽而深的犁沟。施加超声后，随着振幅增大，接触面上的黏着磨损面积与深度先减小后增大，振幅增加至28 μm时黏着磨损程度达到最低，相较普通压装分别降低85.8%、82.1%。此外，磨痕表面的犁沟宽度与深度的减小趋势在振幅达到28 μm时趋于平稳。由于组件接触面间存在振动，该振动将产生大量摩擦热，因此组件接触面出现烧蚀，当振幅高于41 μm时，烧蚀程度从局部轻度演变为大面积重度。结论 在一定超声振幅下，随着振幅增加，超声振动能降低组件接触面间的摩擦力并提高接触面质量，振幅为28 μm时对改善高应力装配接触面质量效果最佳。 |

| The assembly research of the aero-engine fan disk group is very important. The assembly quality of the engine fan disk group directly affects the reliability and safety of the engine. In this study, the ultrasonic vibration-assisted pressing method is used to improve the excessive friction and serious wear between the contact surfaces of the fan disk group caused by traditional manual assembly, which affects its assembly efficiency and assembly quality. The purpose of this study is to clarify the influence of different ultrasonic amplitudes on the friction and wear between the contact surfaces during the high-stress assembly process of the fan disc group. Firstly, aiming at the high stress assembly process of the fan disk group, the mathematical model of contact sliding and the wear model of asperity on the contact surface are established. The theoretical innovation and analysis of friction force and wear degree between friction pairs under ultrasonic vibration are carried out by analytical method. Then, on the ultrasonic vibration assisted press-mounting test platform, an ultrasonic press-mounting test is carried out based on the test components simulating the fan disk group structure. The friction between the contact surfaces of the components under different ultrasonic amplitudes is recorded, and the friction reduction rate is obtained by comparing with the ordinary press-mounting, and then it is compared with the theoretical model. Finally, the wear morphology and wear degree of the contact surface are observed by scanning electron microscopy, and the contact surface material is tested by EDS spectrometer. The results show that when the ultrasonic amplitude is 15 μm, 28 μm, 41 μm and 58 μm, compared with the ultrasonic amplitude of 0 μm, the friction force between the contact surfaces of the components is reduced by 21.9%, 22.6%, 41.1% and 58.9%, respectively. The friction force gradually decreases with the increase of the amplitude, and the friction reduction effect is remarkable. The theoretical model is verified to have high accuracy and can be used to predict the change trend of the friction reduction rate with the speed ratio in the actual pressing process. When the ultrasonic amplitude is 0 μm, there is obvious adhesive wear on the contact surface, and there are wide and deep furrows on the surface of the wear marks. After applying ultrasound, with the increase of amplitude, the area and depth of adhesive wear on the contact surface decrease first and then increase. When the amplitude increases to 28 μm, the degree of adhesive wear reaches the lowest, which is 85.8% and 82.1% lower than that of ordinary pressing. In addition, the study also finds that the width and depth of the furrow on the surface of the wear scar first decreases with the increase of the amplitude, and tends to be stable when the ultrasonic amplitude reaches 28 μm. Because the contact surface of the component is affected by the longitudinal amplitude, the area of repeated friction increases, and the heat in the contact area of the component surface increases greatly at the same time, so the ablation occurs on the contact surface of the component. When the amplitude is higher than 41 μm, the degree of ablation changes from local mild to large area severe. By comparing the material element analysis of the non-ablated and ablated parts of the contact surface of the test piece, it is concluded that the ablation phenomenon is a rapid oxidation reaction that occurs under certain temperature conditions. Through the combination of theory and experiment, the key conclusion is drawn: ultrasonic vibration has an anti-friction effect, and ultrasonic amplitude is the main factor affecting the anti-friction effect. Under certain ultrasonic amplitude, with the increase of amplitude, ultrasonic vibration can reduce the friction between the contact surfaces of the components and improve the quality of the contact surface. When the amplitude is 28 μm, it has the best effect on improving the quality of the high-stress assembly contact surface. The research results provide theoretical guidance and technical support for improving the assembly efficiency and quality of aero-engine fan disk assembly. |
