Model for calculation
When frequency ratio λ In case of large changes, such as wide band excitation and machinery with large weight changes, the use of nonlinear vibration isolation system can achieve better vibration isolation effect. In the vibration isolation design, the parameters and structural type of electric butterfly valve shall be determined according to the size, direction and frequency of the vibration source, as well as the size, weight and vibration isolation requirements of the machinery to be isolated
Purpose and structure of electric butterfly valve Electric butterfly valve is mainly used to restrain the vibration of butterfly valve after shock absorption and rebound and the impact from road surface
