摘要

针对民用航空涡扇发动机中央传动齿轮箱弧齿锥齿轮,存在因结构和质量限制而导致齿轮振动裕度不足等情况,对弧齿锥齿轮开展了动应力计算分析并进行试验验证。仿真分析包括对锥齿轮进行了模态和频响分析,研究了锥齿轮的振动规律;试验采用贴应变片的方法,得到了锥齿轮工作状态下的动应力。结果表明,试验结果与理论计算分析较吻合,动应力计算方法、动应力测量方法可行。

Abstract

The inlet gearbox spiral bevel gear of aircraft turbofan engine may result in insufficient of gear vibration margin because of the limitation of structure integration. The numerical analysis and test research of the dynamic stress of spiral bevel gear are carried out. The simulation analysis of bevel gear includes modal and frequency response analysis,the vibration rules of bevel gear is studied. The dynamic stress of bevel gear under working condition is got by using the method of strain gauge in test. The result show that theoretical analysis fits well with experimental results. The methods of dynamic stress calculation and experimental test are feasible.
