摘要 以某矿用铰接式自卸车车架为研究对象,对其动态特性进行了详细的研究。通过模态分析,得到了车架的前6阶固有频率和振型等模态参数。将分析结果与发动机及路面激励进行了比较分析,结果表明整个车架满足动态特性的条件,符合车架设计的要求,所得结论为该车架的改进设计提供了参考和依据。 Taking a mining articulated dump truck frame as the research object,its dynamic characteristics were researched in detail.By modal analysis,the first 6 natural frequencies and mode shapes of the frame were obtained.The modal analysis results were compared with the engine and road excitation,showing that the frame's characteristics meet the dynamic conditions,as well as corresponding to the requirements of frame design.The conclusions can be used in the improvement design for the frame as theory reference and basis.
