摘要
在完成了基于实验对比的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的有限元分析模型 ,采用Lanczos法对零部件及整机组合体多方案的自由模态进行了计算 ,并由计算结果对修改方案的动态特性进行了初步评价。
Based on the convergence analysis of discrete errors on the basis of comparison with experiment, a V6 diesel engine's finite element models of its chief components and assembly have been established. Adopting the Lanczos method, their free free modal computations have been conducted. Evaluations have been made on the dynamic characteristics of the modified scheme, and conclusions drawn from the analysis have been successfully adopted in the redesign of the diesel's structures
