摘要
运用有限元法对半挂车车架进行了模态分析,得出结构各阶固有频率及振型,比较车架受到的外部激振频率,避免产生共振,造成车架被损坏的危险,评价了半挂车车架结构设计的合理性。
Using the finite element method of semi-trailer frame modal analysis is carried out to get the natural frequency and vibration mode of the frame,comparing the external excitation frequency to avoid resonance,the dangerous frame was damaged,to evaluate the rationality of semi-trailer frame structure design.
