Abstract

Dynamic analysis of hammer mill was carried out using FEM, and dynamic characteristic parameters such as natural frequency、vibration mode and unbalance response were obtained. The various structure parameters that had effect on the dynamic characteristic of rotor were analyzed based on sensitive analysis.Using the weight of rotor and unbalance vibration response as the state variable, and using the nature frequence of rotor as the objective function ,the rotor’s structure was optimized. The result of optimum design indicated that the dynamic performance of rotor has been significant improved. It provides an effective method to solve the vibration problem of hammer mill.
