摘要
运用HYPERMESH有限元分析软件建立了某重卡车架的模态分析有限元模型,计算得出该车架前10阶固有频率和固有振型,将计算结果与汽车受到的激励频率对比分析,讨论了车架在外部激励作用下可能发生共振的情况。
A finite element model of heavy-duty truck was created in HYPERMESH software for modal analysis, the top ten natural frequency and corresponding modal type of the frame was calculated, compared the result with external excitation frequency of the truck, and discussed the situation of the frame may happen resonance.
