| 摘 要： | 在离散误差收敛性分析的基础上,建立了某军用V型柴油机主要零部件及整机结构的有限元分析模型。采用Lanczos法对零部件及整机组合体的自由模态进行了计算,得到了其固有频率和振型,通过振型分析,找到了整机振动的薄弱部位,从而为柴油机结构的改进设计及整机的动态响应分析提供了可靠的依据。 |

| Abstract: | Based on the convergence analysis of discrete errors,the finite element models of V-typed diesel main parts and structure were established.The natural frequency and vibration mode were acquired by calculating the free mode of parts and assembly with Lanczos method.The weak parts of engine vibration were found by the vibration mode analysis,which provided the reliable reference for the modification of diesel structure and the analysis of dynamic response. |
| Keywords: | diesel finite element methods modal analysis |
