Study on the Impact of Braking Force Difference on Longitudinal Force of Heavy Haul Train Under Smaller Pressure Reduction
In order to study the impact of braking force difference on the longitudinal force of heavy haul train,this article analyzes the influencing factors of braking forces of vehicles and the causes for braking force difference between vehicles.Taking C80B car for example,the fluctuating range of influencing factors are analyzed and the coupler forces corresponding to different braking forces in difference distribution cases are simulated and calculated.According to the calculation result,compared with the uniform distribution of braking forces in average value,the random distribution of braking forces of vehicles within the difference range has smaller impact on the longitudinal force of train;if the train is divided into n parts(n≥2)according to the difference of braking forces of vehicles,the smaller the n is,the greater the longitudinal force of train is,while the larger the braking force difference is,the greater the longitudinal force of train is.
