【摘要】 随着计算机软硬件技术的发展,有限元分析技术得到了广泛应用。首先介绍了仿真分析的理论基础及有限元模型建立的一般过程,建立了该发动机悬置的有限元模型。然后对发动机支架进行强度分析,得到了发动机支架需要满足的强度要求。计算所得悬置的刚度与试验结果基本吻合,验证了该模型的有效性,为工程设计提供依据。更多还原

【Abstract】 As the development of software and hardware of computer,finite element analysis has a wide application.It adopt finite element analysis to the engine bracket.The theory of simulation analysis and the process of the building of the finite element model are introduced,and then analyzed the strength of the engine bracket to get the engine bracket need to meet the strength requirements,suspension stiffness and the calculated basically consistent with experimental results to verify the validity of the model.A basis for engineering design is provided.更多还原
