隧道交会工况下城际列车横向偏移量影响研究
Research on the Influence of Lateral Deviation of Municipal Trains under Tunnel Intersection Conditions
摘要
Abstract
To investigate the factors influencing the lateral displacement of intercity trains during head-on encounters within tunnels,aerodynamic and multi-body dynamic models of a specific intercity train were established.Utilizing principal effect analysis and nonlinear multiple regression analysis,the research explored the impacts of train speed,track gauge(or distance between tracks),and train load on the lateral displacement of the train body.A power function-based multiple regression equation was also developed.The research re-sults show that under the condition of constant-speed encounters within tunnels,the later-al displacement of the train body positively correlates with train speed and negatively cor-relates with track gauge and train load.Among these factors,train speed has the greatest influence on lateral displacement,followed by train load,while track gauge has the least impact on train displacement.关键词
