摘要
凯恩法是一种适用于建立公路车辆列车机组运动数学模型的多刚体动力学分析法,具有推导方便、通用性好、便于用计算机求解等优点。本文用它建立了一个包括半挂或全挂车辆列车机组的多自由度非线性动力学模型,给出了用此模型对泰山-25型拖拉机运输机组进行操纵稳定性动态模拟的实例。
Kane is a new multi-body dynamic analysis method which is suitable to the modeling of vehicle train combinations,having advantages of easy developing,good in common use,and suiting integration on computer,An nonlinear dynamic model of vehicle train combinations which includes tractor- semitrailer and truck-trailer is established by using this method.Simulation example of the handling characteristics of Taishan-25 tractor and trailer combinations based on this model is given.
