摘　　要：针对某拖拉机动态环境噪声问题,通过分析该拖拉机的动态环境噪声和瞬态固定挡位匀加油门工况下噪声的频率和阶次,确定了后中央传动锥齿轮副啸叫是引起拖拉机动态环境噪声超标的主要因素,为下一步拖拉机降噪工作的开展提供了依据和参考。Aiming at the problem of the dynamic environment noise of a tractor,this paper analyzed the tractor’s dynamic environment noise and the frequency and order of signals under transient operating condition of fixed gear uniform throttle.The results show that the whine noise of rear central transmission bevel gear pair is a main factor causing the dynamic environmental noise exceed the standard,which provides basis and reference for the tractor noise reduction in the next step.

关 键 词：拖拉机 动态环境噪声 阶次
