| 摘 要： | 针对某发动机缺乏外场地面试车振动监测限制值,严重影响安全使用的客观事实,在对该型发动机结构特点分析的基础上,借助于转子动力学有限元技术,建模分析了该发动机的转子动力学特性,明确了应重点监测燃气涡轮机匣处振动,为外场振动实测提供了理论指导.结合大量的外场实测振动数据分析,基于旋转机械振动监测限制值确定的通用原则,初步给出了工程适用的外场地面试车振动监测限制值建议.

| Abstract: | The study was taken in order to evaluate vibration limit value for an aeroengine and to improve its safety in utilization. Based on the analysis of characteristics of the engine structure and its rotor bearing, a model was built by means of rotor dynamics finite element methods. The dynamic performance of engine rotor was investigated. It points out that gas turbine case is key point for vibration monitoring. Field vibration tests were carried out according to the findings. Vibration data were fully studied. According to principles for rotating machinery vibration standards, the vibration limit values for field ground test were put forward, which was suitable to engineering. |
