Control mode curve is crucial for train control system to generate effective train control strategies, guarantee not only the train's safety but also efficient operation. With the improvement of train speed, harsh requirements for train control system and Complex running environment are put forward. Therefore, the study of high-speed railway's control and simulation theory is of great significance for train's safety and timeliness. What's more, the study of train control and simulation can provide plenty of important basic theory for high-speed railway's optimal control and multi-target train running control model's research. On the basis of train control and simulation, the paper focuses on high-speed trains running control under complex environment, the design and development of high-speed train operation control mode curve simulation software, the verification of control mode curve algorithm's feasibility. The paper's research emphasized on several aspects as follows:(1) Firstly, the present status at home and abroad of simulation and optimization on train control operation process was introduced. Centering on basic theory of train control, train control dynamics theory and principle of operation process were introduced. Therefore, train control mode curve based on train dynamics theory was researched.(2) Algorithm of high speed train control mode curve was brought up by analysis on the single particle model, and combined with theory of train control dynamics theory according to the most rapid speed control strategy. On the basis of the multi-particle train simulation model, railway partition model and train force algorithm in grade switch section are designed. Considering the three representative train control operation process, the mathematical model was established and control scheme was proposed.(3) Finally, the general scheme of high speed train control mode curve simulation was introduced in detail, and simulation system was established, the system program development and interface were completed. By constructing various simulation scenes, high speed train control mode curve algorithm was analyzed and verified under different routes, environmental and train model conditions based on the simulation system.The conclusions indicate that control mode curve algorithm based on different conditions is of feasibility and adaptability for high speed train.
