本文采用三维有限元法对一个具有4000多自由度的高速内燃机车车体进行了模态和在柴油机垂向激振力作用下的动力响应分析.在有限元离散模型的建立以及模态分析方面作了进一步的分析探讨.
In this paper, a three-dimensional finite element method is used to analyze the dynamic response of a high-speed diesel locomotive body with 4000-DOF high-speed diesel locomotive under the action of vertical excitation force of diesel engine. In the establishment of finite element discrete model and modal analysis Made further analysis and discussion.
