摘　　要：转向架为矿用自卸车的重要组成部分,用来改变或恢复其行驶方向。为提升转向架的静强度、疲劳强度、可靠性等性能,使用SolidWorks软件建立底卸式矿车转向架三维实体模型,然后将三维实体模型导入ADAMS软件中的Vibration模块计算得到底卸式矿车转向架前19阶固有频率。仿真分析表明,转向架振动频率从2.098 Hz开始到2.3478 Hz之间形成一个阶段性的振动波峰并发生共振现象,接着转向架振动逐渐趋向于和缓。直至在8.3418 Hz形成相比于前一个更大的振动波峰,再次发生共振现象,之后转向架振动逐渐趋向于和缓。该结果为后续转向架结构优化、平顺性研究及改进设计提供了理论参考。Bogie is an important component of mine drop-bottom car,and is used to change or restore their driving direction.To improve the static strength,fatigue strength,reliability and other performance of the bogie,SolidWorks software was used to establish a 3D solid model of the drop-bottom mine car bogie.Then,the 3D solid model was imported into the Vibration module of ADAMS software to calculate the first 19 fixed frequencies of the drop-bottom mine car bogie.Simulation analysis shows that the bogie vibration frequency forms a periodic vibration peak between 2.098 Hz and 2.3478 Hz,leading to resonance phenomenon,and then the bogie vibration gradually tends to become gentle.Until a larger vibration peak is formed at 8.3418 Hz compared to the previous one,and resonance occurs again.Afterwards,the bogie vibration gradually tended to be gentle.This results provide theoretical reference for subsequent optimization of bogie structure,smoothness research and improved design.
