在结构模态分析理论的基础上,运用I-DEAS软件建立了整车液压缸换级冲击载荷和脉动风载荷的数学模型,完成了车辆结构的模态分析,由此得出了结构受到外界激励时的振动幅度、频率,所得结果可指导设计改进。
Based on the theory of structure modal analysis, a mathematical model of the vehicle cylinder displacement shock load and fluctuating wind load was established by using I-DEAS software, and the modal analysis of the vehicle structure was completed. When the vibration amplitude, frequency, the results obtained can guide the design improvement.
