【摘要】：采用超单元技术处理与车架相连的履带部分模型,并用拓扑优化方法对起重机车架的结构进行重新设计。结果表明,超单元法与传统的全模型分析法相比,求解精度相同,而计算时间仅为全模型分析法的1/3,达到了节省计算时间且保持计算精度的目的。最后通过有限元分析和疲劳试验验证了利用超单元法处理复杂模型的可行性。
[Abstract]:The part of track model connected to the frame is treated by using the technology of superelement, and the structure of crane frame is redesigned by topology optimization method. The results show that the accuracy of the method is the same as that of the traditional total model analysis method, and the calculation time is only 1 / 3 of that of the whole model analysis method, which achieves the purpose of saving calculation time and maintaining the calculation accuracy. Finally, the feasibility of using superelement method to deal with complex model is verified by finite element analysis and fatigue test.
