According to the principle of static and dynamic balance, using a hammer to change the axis of the layout in the original non-symmetric static and dynamic balance changed to be easier to establish symmetry with staggered, and the use of the traditional method of checking the balance of the improved rotor were checked, Basically, in order to set up the static and dynamic balance. Taking into account the size and imbalance unbalance location of the vibration of rotor system; check the structural strength, by the base structure of the value of static stiffness and dynamic stiffness values. Analysis of results showed that the imbalance of the whole intensity of the shock and have a greater impact. Application of mechanical optimal design theory, to explore the use of static and dynamic balance between the principle of dynamic optimization of structural design and optimization of a significant effect; final hammer against the impact of the dynamic characteristics of machines and other factors, the measures proposed by the vibration. The conclusions for the mill products, as well as noise and vibration reduction design of static and dynamic balance of rotor check and provide a theoretical basis, through the hammer mill on the structural dynamic optimization design study for future similar to the type of optimum design of rotating machinery to provide a reference works. Keywords: hammer mill； dynamic characteristics；dynamic optimization of the design； static and dynamic balance. II
