摘要
本文介绍了一种基于整机链式分析的发动机FBO载荷评估方法,该方法能将由显式动力学分析得到的冲击和碰摩载荷通过链式分析的载荷传递工具传递给隐式动力学分析。链式分析相比单纯的整机显武动力学分析或整机隐式动力学分析,能更真实和全面地反映整机结构在风扇叶片脱落后的响应。
A method of load evaluation for FBO eventbased on full-engine chained analysis is introduced in this article.In this method,the impact and rubbing loads derived from explicit analysis is transferred to implicit analysis with a load transfer tool.Compared with the mere explicit or implicit full-engine analysis,the chained full engine analysis can provide a more realistic and comprehensive prediction for the engine structure response after FBO.
