低压涡轮初始不平衡量超限计算分析与排除
|
摘要
针对某型航空发动机低压涡轮转子初始不平衡量超限问题,根据机件形位误差与不平衡量之间的影响关系进行计算分析,得出当支承锥盘与盘片组件间形位误差和低压涡轮盘片组件定位基准误差处于极限值且为不利组合时,引起的转子不平衡量值远大于或接近7500 g·mm限制值。根据计算结果,并按照效率最高原则及科研装配经验,制定了排除低压涡轮初始不平衡量超限流程,实践检验方法有效。研究结果表明:控制转子定位基准误差,减小组合件装配形位误差,根据转子不平衡量数值调整机件间安装相位,是降低和优化转子初始不平衡量的有效手段。
In order to solve the overrun problem of initial unbalance of an aeroengine low pressure turbine rotor,the calculation and analysis were carried out based on the influence relationship between geometric error and unbalance of aircraft parts. It was concluded that when the geometric error between the supporting cone and the disc assembly and the positioning datum error of the low pressure turbine disc assembly were at the limit value with unfavorable combination,the caused rotor unbalance amount was much larger than or close to the limit value of 7500 g·mm. According to the calculation results,the maximum efficiency principle and the experience of scientific research assembly,the flow path of eliminating the initial unbalance of low pressure turbine was constituted,and the practical test method was effective. The research results show that improving the datum error of the rotor positioning,the geometric error of the assembly parts and the installation phase among the components based on rotor unbalance value is an effective means to reduce and optimize the rotor initial unbalance.
