摘　　要：机架结构共振是造成转页扇振动大、产生异音的主要原因,通过测试分析某款转页扇的振动,应用ANSYS Workbench软件对其进行模态仿真与谐响应仿真分析,对机架结构进行优化设计,提高支撑筋扭转固有频率,有效避开电机100 Hz激励频率,明显改善转页扇的振动。研究结论对同类家电产品的振动分析与正向设计有一定的参考价值。Fan rack structure resonance is the main reason of large vibration of the rotary fans and the abnormal noise. In this paper, the vibration of a rotary fan is measured and analyzed. The modal simulation and harmonic response simulation are carried out by means of ANSYS Workbench software. The rotational natural frequency of the rotary fan is improved by optimizing the rack structure to effectively avoid 100 Hz frequency of motor vibration. The rotary fan vibration is obviously reduced after the improvement. The research may have some reference values for vibration analysis and design of similar electrical products.
