Abstract
In view of the study of topology optimization design method on vibration and noise reduction of damping sandwich circular saw, the optimal thickness and layout of damping material were obtained. The optimization model of circular saw was established by using the coupling method, the optimum thickness of damping layer was found. By using ESO method, deleting elements method and modal loss factor sensitivity calculation method were obtained. Making use of modal loss factor sensitivity, ineffective elements were deleted by judging the whole structure damping effect on each damping material element, optimal configuration of damping sandwich circular saw structure under the stiffness condition was obtained, which reduced the vibration and noise and reached a certain stiffness requirements. By contrasting the damping loss factor of three different circular saw models, the results show that optimized circular saw structure has the best damping effect.
