摘要
本文用多连键图技术来模拟一铁道车辆系统,该系统具有17个自由度。通过编写子程序将非线性的轮轨相互作用力定义为子模型,与系统的键图模型相连接。最后,本文对车辆以恒速在圆曲线轨道上运行的动力学特性进行了简单的分析计算。
A railway vehicle system is described using multibond graph technique. The mathematical model of the system has 17 degrees of freedom. The nonlinear wheel-rail interaction forces can be included in the bond graph model as submodels which are defined by writing subroutines. The dynamic simulation of the vehicle running on a curved track of constant radius with constant speed has been investigated.
