摘要
简要介绍了用模态分析结果修改结构有限元模型的“设计参数修改法” ,以某大功率柴油机的缸盖为例进行了验证。计算和分析结果表明 ,利用设计参数修改法修改后的有限元模型能够比较准确地反映结构的动态特性。
Design parameter modifying method'of modifying finite element model by modal analysis result is introduced briefly in this paper. It is validated by the cylinder head of a heavy duty diesel as a sample. The calculation and analysis result show that the finite element model modified by this method is able to reflect the structural dynamic characteristics accurately and that this method possesses rather reliability.
