| Abstract: | To reduce the vibration level of the fuselage, the focul fluid elastomer vibrati
on isolation system, which can effectively isolate the vibration load from the r
otor,is put forward.By modeling the fluid elastomer vibration isolator and the f
ocul vibration isolation system,the dynamic characteristics of the focul fluid e
lastomer vibration isolation system are analyzed. The influences of damping, installation angle and tunning fluid mass on transmissibility are discussed. |
