Study Of Automatic Function Of Speedup Train Traction Calculation Software

The calculation of train running speed and its zonetime is the main function of train traction calculation software. When the current train traction calculation software calculate train running speed and its zonetime, it can be only done by manual simulated train driver operating and spend a lot of manpower, material resources and time. The mass speedup in train brings forward needs of automatic function in calculating train running speed and zonetime with computer to the current train traction calculation software. It is urgent for locomotive department to exploit new train traction calculation software possessing automatically calculating function and to get results according with manual calculating results. The article's research was based on the fifth mass speedup of train, having practical significance. The main contents of the article are followings:1. Based on various effects on train running imposed by operation conditions, inducting the definition of speedup ramp to deal with rail vertical section in process of deciding controlling tactics, expounding the relationship between train running speed and rail condition and train running state, and showing the effect of train running speed by ramp.2. Exploring the applied methods of the multiple model fuzzy integrated control theory in automatically calculating train running speed and zonetime, and seeking for better methods and approaches.3. To decide the basic principals, tactics of conditional choice and conversion and study automatically calculating methods and given situation and form automatically calculating control value of train running process through all kinds of basic tactics according to the best ability running conditions of the speedup train, combined with the optimized operating experience, to design automatically calculating module process of train traction calculating software and realize automatically calculation function.4. To calculate train running process of deferent teams, limited speed condition and running route utilizing automatically calculating function, to testify the validity, correctness and practicability of the automatically calculating function of train traction calculation software according to the contrastive analysis of automatically and manual cases.
