摘要
将飞机压力加油系统管路简化为两端简支的连续梁模型 ,分析了系统管路固有频率特性以及其与系统导管卡箍固定位置的对应关系。根据油泵的工作状态 ,分析了管路发生共振的频率范围 ,确定了系统导管卡箍固定间距的安全范围。
We simplified the pipelines of the aircraft ground pressure refueling system to a continuous beam model, analyzed the natural frequency of the pipeline system and its correspondent relation with the fixture interval of pipe hoops. According to the oil pump′s work conditions, We analyzed the frequency range in which the pipelines can resonantly vibrate, and determined the range of fixture intervals for safely refueling.
