Simulation of Pressure and Flux of a Multi-line Variable-pressure Oil-separation Unit on Gear Test System

  • 摘要: 根据齿轮驱动风扇构型的航空发动机试验时风扇驱动齿轮箱试验件各滑油喷嘴精确供油要求,在液压加载式功率流封闭齿轮试验台供油路上加装了一个可以多路变压力分油的分油装置,分油装置内腔设计多条油路支路,在支路上安装有节流元件,通过调节节流内孔孔径和长度控制节流元件压降,向试验齿轮箱各滑油喷嘴提供多路不同压力的滑油,使得试验齿轮箱滑油喷嘴流量和流速精确达到试验要求。采用Flowmaster软件对试验台滑油供油系统进行了一维稳态仿真分析,分析了节流元件内孔长度和孔径对试验齿轮箱滑油喷嘴流量和流速的影响作用。结果表明:节流内孔孔径对节流元件压降的影响远大于节流内孔长度对节流元件压降的影响,特别是当节流内孔孔径在1 mm至3 mm之间时,节流元件对滑油供油流路压力具有明显的调节作用。
