| 摘 要： | 针对气缸盖在工作中承受交变载荷,容易形成疲劳损坏的现象,介绍了一种快速有效的方法来计算气缸盖的疲劳寿命.首先利用Hypermesh软件建立了有限元模型,针对不同区域设置了不同的单元密度,并通过有关参数来控制网格的质量.然后利用Abaqus软件分别计算了气缸盖的温度场、稳态应力场和耦合应力场,在温度场的计算中,将燃烧室火...

| Abstract: | Aiming that the cylinder head is easy to form fatigue damage when under the alternating load,a rapid and effective method to calculate the fatigue life of the cylinder head was introduced.Firstly,the FEM-model of the cylinder head was built by using Hypermesh software with arranging different density of elements and the element quality was guaranteed with the mesh parameters.And the temperature field,the steady-state stress field and the coupling stress field of the cylinder head were calculated by using Ab... |
