摘要
针对新设计的某型柴油机缸体,用CAD建立缸体的三维有限元模型,采用大型有限元软件ANSYS,对缸体进行了模态分析,得到了缸体的固有频率和振型,为今后进行缸体动力响应计算奠定了基础。
The dynamic properties and the vibrational response of the cylinder body do affect the diesel engine a lot. As one of the basic analyses, the modal analysis is mainly used to get the dynamic properties of the structure. The 3D finite element model of the cylinder body is established by the CAD software, and its mode is calculated by the ANSYS, then the premise of the dynamic response of the cylinder body is established.
