摘要
以中国第一座直升机旋翼试验塔为研究对象,建立了塔体的动力学有限元模型,对塔体的模态频率和振型进行了计算,并对塔体在旋翼动载荷作用下的响应进行了计算,最后探讨了旋翼塔对旋翼试验可能造成的影响。
This paper researches the first helicopter rotor whirl tower in china. Dynamic finite element model is built, and the model vibration and frequency of the tower shell is calculated. The response of the tower shell under the action of the rotor dynamie load is calculated. The influence of rotor whirl tower on rotor test is discussed.
