某直升机旋翼动平衡试验台结构动力学分析

Dynamic analysis on the structure of one experimental bench for dynamical equilibrium test of the helicopter's rotor wing

运用有限元软件ANSYS对直升机旋翼动平衡试验台系统的振动与响应特性进行比较全面的分析,以准确反映试验台系统在电机传动系统带动直升机旋翼旋转时产生的一定频率的力对系统与系统中各部件的影响,从而为避免系统因共振等原因造成的损坏在理论上提供参考,为改进设计提供依据。

Thoughly analyzing to the structure of one experimental bench for dynamical equilibrium test of one helicopter＇ s rotor wing by finite element method, the paper accurately reflects the affects of the forces with certainly frequency to the test bench of rotor wing, when the test bench of rotor wing revolvs by the electro-mechanic driving system. It provids the foundation in the theory, in order to avoid damage of system resonance and the other causes.
