| description | Because of the higher viscosity and good thermal stability， the dimethyl silicone oil is considered as a damping fluid for integral squeeze film damper （ISFD）. The influence of damping fluid’s viscosity of ISFD on the vibration reduction characteristics of gear shafts is studied. The mechanical model of ISFD elastic damping bearing system and the damping single-degree-of-freedom vibration system of the gear system are established， which shows the effectiveness of ISFD in vibration reduction of gear shafts. A first-grade spur gear bench is built to compare the vibration of the gear system with rigid support and ISFD elastic damping support with different viscosity damping fluids. Experimental results show that ISFD with a damping fluid of dimethyl silicone oil can effectively inhibit the vibration of gear shafts， and the decline of vibration amplitude is more than 50%. With the increase of viscosity of ISFD damping fluid， the decline amplitude of gear shafts vibration increases. The ISFD with a damping fluid of dimethyl silicone oil has excellent damping vibration attenuation characteristics， which can effectively reduce the vibration of various frequency components and guarantee the smooth operation of the gear transmission. |
