| Abstract: | Rotor head absorber is a new kind of vibration reduction device for helicopter,which provides some advantages in applications.In the paper the mechanical model for analysing and designing such kind of device is presented,and two analytical methods(frequency domain and time domain)and its adaptability are studied.At the same time,the characteristic of rotor head absorber is analysed.The deduced rotor receptance proved by model test is presented. At last the effectiveness of mechanical model,analytical methods, and such type of absorber presented in the paper are illustrated in the calculation example. |
