Track irregularity is one of the factors that make the increase of car body vibration, wheel-rail interaction force and wheel-rail noise.

轨道不平顺是引起车体振动加速度、轮轨作用力和轮轨噪声增大的主要因素之一。

The nonlinear wheel-rail interaction forces can be included in the bond graph model as submodels which are defined by writing subroutines.

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。
