| 中文摘要: |
| 液压联轴器在工作过程中通过内轴和外套的接触碰撞传递扭矩，从而可能产生共振等现象。为此，针对液压联轴器内轴与外套的碰撞进行振动研究。首先利用UG软件对某型号液压联轴器进行三维建模；然后将其导入Workbench进行模态分析，得到前6阶模态振型和固有频率；最后基于模态叠加法下对液压联轴器的内轴和外套分别进行谐响应分析。结果表明:液压联轴器内轴在低频率下出现共振，而外套在高频率下出现共振。 |

| Hydraulic coupling transfers torque through contact and collision between inner shaft and outer sleeve in working process, which may cause resonance and other phenomena. For this reason, the vibration research of the collision between the inner shaft and the outer sleeve of the hydraulic coupling is carried out. Firstly, UG software is used to build 3d model of a hydraulic coupling. Then it is imported into Workbench for modal analysis, and the first six modes and natural frequencies are obtained. Finally, based on the modal superposition method, the harmonic response analysis of the inner shaft and outer sleeve of the hydraulic coupling is carried out respectively. The results show that resonance occurs in the inner shaft of hydraulic coupling at low frequencies, while resonance occurs in the outer sleeve at high frequencies. |
