摘　　要：为了促进甲醇燃料在汽油发动机上的使用,通过把18K4G汽油机的缸垫改为局部带有小孔的强化缸垫,可强化甲醇燃料混合气点燃工作。利用CATIA软件建立缸垫的三维模型,利用ANSYS软件对缸垫进行静力学、模态、瞬态动力学和寿命仿真分析,并以缸垫不同部位的厚度为变量进行了结构轻量化。结果显示,缸垫质量减少了5.6%,为进一步研究缸垫的新结构对甲醇燃料混合气的强化燃烧奠定基础。In order to promote the use of methanol fuel in gasoline engine,by changing the cylinder pad of 18K4G gasoline engine to the reinforced cylinder pad with local holes,the ignition work of methanol fuel mixture can be strengthened.Using CATIA software to build the three-dimensional model of the cylinder cushion,and using ANSYS software to simulate and analyze the statics,mode,transient dynamics and life of the cylinder cushion,the structure is lightened with the thickness of different parts of the cylinder cushion as a variable.The results show that the mass of the gasket is reduced by 5.6%,which lays a foundation for the further study of the new structure of gasket.
