摘要
本文以某直升机的研制为背景,在设计过程中借助大型标准通用分析软件MSC/NASTRAN对此直升机的全机动态特性进行了有限元分析,计算结果与后续的全机动态特性试验结果比较,主要的固有频率值吻合较好,为全机的结构动态特性设计提供了依据,并且验证了理论分析的正确性。
In this paper a finite element analysis of helicopter dynamic behavior taking a designed helicopter as target has been carried out by using MSC/NASTRAN. The predicted results show good agreement with test ones for the main frequencies and modes, which verified the helicopter structure modeling and dynamic design.
