内燃机车救援动车组纵向动力学性能研究
Research on Longitudinal Dynamic Performance of Diesel Locomotive Multiple Units for Rescue
摘要
Abstract
To study the longitudinal dynamic performance of diesel locomotive multiple units named Fux-ing for rescue under braking conditions,the detailed numerical model of the train-coupler system was es-tablished and the actual kinematic relations and hysteresis characteristics of the coupler gear model were considered.Then the dynamic response of the coupled rescue multiple units and the coupler/draft gear system under emergency braking,service braking as well as the vertical curve passing conditions were an-alysed.Through the research mentionaed above,the dynamiz ersponse between the vehicle system and the coupler system was obtained and the threshold value of the braking level was formulated.The calculation shows that it is feasible when the coupled rescue Fuxing multiple units runs at a speed of over 40 km/h,the emergeny braking can be conducted on a long ramp way with an angle smaller than 15％o.关键词
