| 摘 要： | 本文采用机械阻抗测试方法,试验分析了某发动机的后支承安装条件,即螺栓拧紧力矩及配合间隙对支承机匣系统共振频率及位移导纳值的影响。试验结果表明,安装条件的影响局限在一定范围内。故在规范范围内,改变安装条件,可在一定程度上调整发动机的振动。 |

| Abstract: | The method of measuring mechanical impedance is used to analyse and investigate the effect of installing conditions of a rear bearing of an engine case, that is the screwing torque and the joining gap of connecting boltson the resonant frequency and displacement mobility. Experimental results show that the installing conditions have an effect on them to a certain extent. Therefore, changing the installing conditions may adjust vibrations of an engine within a small range. |
| Keywords: | engines engine case dynamic characteristics installation. |
