摘要
车架在汽车运行过程中,受到各种动载荷的激励。文章利用ANSYS workbench对某载重货车进行了模态特性分析,得到了其前六阶振动频率,给出了相应的变形云图和最大变形量,分析了路面和发动机激励与车架共振频率的关系。
The frame is motivated by various dynamic loads during the running of the automobile. In this paper, the ANSYS workbench software is applied to analyze the modal characteristics of a truck. The preceding six-order vibration frequency is obtained. In addition, the corresponding deformation cloud map and maximum deformation are given. The relationship among road excitation, engine excitation and frame resonance frequency is analyzed.
