The invention provides a motion parameter correction calculation method and system for motion trend change, and the method comprises the steps: obtaining a first unit resultant force corresponding to a corresponding starting position and a second unit resultant force corresponding to an ending position of a train according to a specified calculation step length; when the product of the first unit resultant force and the second unit resultant force is smaller than 0, it is determined that the train operation trend changes, and the inflection point where the resultant force is 0 is determined; splitting the calculation step length into two sections according to the inflection point for correction calculation; and correcting the motion parameters of the termination position according to the first unit resultant force and the second unit resultant force. According to the method, the change of the train running trend in the calculation step length is considered, the motion parameters are corrected according to the resultant force, and the curve simulation precision is improved.
本发明提供一种运动趋势变化的运动参数修正计算方法及系统,方法包括:据指定计算步长,获取列车在对应的开始位置对应的第一单位合力以及终止位置对应的第二单位合力;当第一单位合力与第二单位合力的乘积小于0时,确定列车运行趋势变化,确定合力为0的拐点;将计算步长根据拐点拆分为两段进行修正计算:根据第一单位合力和第二单位合力,修正终止位置的运动参数。本发明考虑了计算步长内列车运行趋势的变化,对运动参数根据合力进行修正,提高了曲线仿真的精度。
