摘要
建立了直升机旋翼动力传动系统扭振的动力学模型,经过计算得出了旋翼桨叶的摆振集合型模态频率和振型,指出动力传动系统会对直升机旋翼摆振集合型模态产生显著影响,使得桨叶的摆振模态频率发生改变,通过直升机旋翼动力传动系统扭振频率试验验证了计算方法和结果的有效性。
The torsional vibration dynamics analytical model of rotor power transmission system is built,the shimmy collectivity mode of vibration and frequency of rotor blade are obtained, it is indicated that the pro-pulsion/transmission system will influence shimmy mode obviously, the frequency of blade shimmy will be changed. Through the torsional vibration frequency test of helicopter rotor power transmission system, method and result correctness are verified.
