Dynamic and acoustic characteristic of a certain mower were tested and analyzed in this paper ,and the corresponding model of mower were made by usingthe finite element and boundary element methods. Vibration isolator to connect motor with mower to reduce radiation noise was adopted . In the optimization design ofvibration isolator,stiffiness and damping were used as variablesand average displacement of mower was used as object function.And the result shows that thenoise is reduced effectively.
