摘要
介绍了ANSYS有限元软件的基本原理以及所使用的SOLID186结构单元的特性,通过ANSYS有限元软件定义耦振模型相关参数,根据图纸尺寸建立某轧机主传动系统及带材结构模型。并对所建模型进行模态分析,得出轧机主传动系统及带材结构模型的固有频率以及所对应的振型。然后进行谐响应分析,得到谐响应分析结果。最后综合模态分析和谐响应分析结果,证明了主传动系统及带材模型在简谐载荷频率为8.4 Hz时,系统结构发生共振。为同类轧机设计和实际生产提供了参考依据。
Basic theory of ANSYS program and the property of SOLID186 structural units are introduced, and the relative parameter of coupled vibration is defined through ANSYS finite element program. The structure model of the main drive system and the strip for a rolling mill is built according to actual blueprint, and modal analyzed. The natural frequencies of the model and its mode shape are obtained, and carried out harmonic re- sponse analysis. Finally, the results proved that system structure begin resonance when the harmonic load fre- quency of the model is 8. 4Hz, the model of the main drive system and the strip. And the results are refer- enced for the design and production of other similar rolling mills.
