摘　　要：缸盖是发动机的重要部件,其性能的好坏直接影响发动机的整体性能,利用HyperWorks软件对某款柴油机缸盖进行了有限元建模和模态分析,得到了缸盖在约束模态下的前六阶振型和固有频率,为发动机减振和降噪提供了理论依据。Cylinder head is the important part of automobile because it directly affects the engine performance. Analysis model of cylintier head was set up to analyze the modals of cylinder head under restricted condition, and get the former six natural frequencies and correspond mode shape, supplie foundation in theory, to improve engine quality.
