Force Analysis and Modeling Study on Multi-Mode Running-Status of Trains
摘要
Abstract
During the running process of the train, various kinds of situations such as ramp way, curve line, straight line or tunnel will appear in the route of the train because of the changes of geographical environment. So the train will be under the actions of different external forces when it runs along the specific route. The author aimed at the multi-mode running-status of the train on the curve line, analyzed the situations of the traction force, resistance and the braking force, and established the rigid-flexible multi-body system structure dynamics model of train on the curve line. Also, the author solved the dynamic differential equations of the train by means of DAE (differential algebraic equations) and ODE (ordinary differential equations) , and put forward the suggestion on integrated parameter optimization of the train.关键词
