摘　　要：为了提高重型履带装甲车辆的平衡肘强度,围绕某履带车辆行驶系平衡肘动态特性研究,以RecurDyn软件为仿真平台建立了某型履带装甲车辆平衡肘刚柔耦合动力学模型。模型充分考虑了平衡肘各方向的柔性特征,并以四种典型路面和不同的行驶速度为输入条件,计算出柔性部件的动态特性,与多刚体系统分析相比,利用刚柔耦合仿真分析的结论更加贴近实际工况。并根据平衡肘的动力学分析对薄弱位置提出结构优化方案,使平衡肘的强度得到了显著提高。研究表明上述方法对优化同类型零部件设计结构,提高结构件强度具有重要的参考价值。In order to improve the balance elbow strength of heavy tracked armored vehicles,dynamic characteris-tics of the balance elbow of a tracked vehicle were studied,a rigid-flexible coupling dynamic model for the balanced elbow of a tracked vehicle was established based on RecurDyn software environment.This model fully considers the flexible characteristics of each direction of the balance elbow and uses four typical roads and different driving speeds as input conditions to calculate the dynamic characteristics of the flexible part.Compared with multi-rigid-body system analysis,the conclusions of rigid-flexible coupling simulation analysis are closer to the actual working condi-tion.According to the dynamic analysis of the balance elbow,the structural optimization of the weak position has re-sulted in significant improvement in the strength of the balance elbow.The research indicates that this method has important reference value for optimizing the design structure of the same type of parts and improving the strength of structural parts.
