采用有限元分析方法,对4100QB柴油机机体不同加筋结构进行了模态分析,分析了不同加筋结构的机体表面在各模态下的振动特性,探讨了增强机体结构强度与刚度的一般方法,为机体优化设计提供依据。
The finite element analysis method was used to analyze the modal analysis of different stiffened structures of 4100QB diesel engines. The vibration characteristics of the stiffened structures with different stiffened structures under different modalities were analyzed. The general methods of enhancing the strength and rigidity of the structure were discussed. To provide the basis for the body to optimize the design.
