摘　　要：以HyperMesh及Ansys软件为平台,对6L16/24型船用柴油机机体进行结构简化,通过手动与自动相结合的方式建立有限元模型。分析内燃机在运转时机体的实际受力,选择载荷加载方式,定义边界条件,为动态应力分析、强度校核及结构优化设计等提供求解及分析模型。Based on HyperMesh and Ansys software,a finite element model of the framework of a 6L16/24 diesel engine was created using manual method associated with auto method after predigesting the structure of it.The actual forces on the framework were analyzed,as well as the manners of loading the forces on the finite element model and the determining the boundary condition.In order to provided a practicable model for the dynamic stress analysis,verification of strength and optimization of the framework＇s structure.
