On the Problem of Dynamic Response of the Long Trains Including Joint Ones with the Liquid Cargo

Abstract

EN: The results of long trains with liquid cargo dynamic response at braking obtained by the mathematical simulations are given in the article. Different approaches of the lead and helping locomotives control are considered for the various schemes of the train make-up. Numerical experiments were carried out for the various types of braking on the horizon-tal track segment and for different regimes of air diffusers work – middle or loaded. The initial motion speeds were equal to 20 and 80 km/h. For the higher speeds the braking distances were estimated. Recommendations on the longitu-dinal dynamic response reduction in the long trains with liquid cargo are given on the basis of the carried out numerical calculations.
