摘要 本文提出一种新的求解列车运行附加阻力的质量断面法,它一改视列车为一质点或刚体的传统计算方法,以整个列车长度与所正运行的线路纵断面为对象,建立起质量断面数学模型,在考虑不同列车编组的情况下,求出不同的系数值,从而求得列车各不同运行位置较精确的阻力值.此方法的计算结果与京原线北屯至小西庄站的实际运行结果吻合较好. A new method named mass and longitudinal road section ispresented in this paper for solving additional resistance of trainworking.It completely changes the traditional calculation me-thods which consider a train as a mass point or rigid body.It takes all train length and the longitudinal road section ofthe train travelling location as studying objects,and presentsa mathematical model of train mass and longitudinal roadusing this model,we can solve for of different coefficient(ai)in considering different train formation,and hence get rather accurate train working resistance value in rations travellinglocation.When the calculating result got by using this methodwas compared with a actual train travelling result between Be-itnn Railway station and Biaoxizhang station of JIN-YUANmain line,there was a good coincidence.
