摘　　要：为提高压丝辊的工作频率范围,对压丝辊结构进行了模态仿真分析和结构参数优化,通过结构参数优化,得到满足压丝辊设计要求的工作频率带宽范围。实验结果表明,优化后的直径85 mm的实心压丝辊结构的各阶模态频率均能避开150~220 Hz工作范围,有效避免了压丝辊由自身结构引起的共振问题。In order to improve the working frequency range of the roller, the modal analysis and the optimization of the structural parameters are carried out. The design frequency range requirements of the roller are satisfied by optimizing the structural parameters. The experimental results show that the modal frequency of the optimized roller with diameter of 85 mm can avoid the working range of 150 -220 Hz. It can effectively avoid the resonance caused by the structure of the roller.
