[Abstract]:With the rapid development of high-speed railway industry in China, high-speed railway line design based on comfort evaluation has become an important link in the overall design of high-speed railway. The level of comfort evaluation directly reflects the merits and demerits of the line design scheme and has important application value in the line design stage. This project faces the high-speed railway line design stage, based on the high-speed train operation simulation theory and the train line dynamics theory, takes the line design scheme comfort evaluation as the research content, introduces the train operation simulation principle in the train line dynamics theory. According to the result of dynamic response of vehicle line, the evaluation index value of comfort degree is solved, and the evaluation of comfort degree of route design scheme is realized. According to the principle of optimal matching design of vehicle and route, the design of line is aided, and the design quality is improved. The main work of this paper is as follows: (1) the traction calculation model based on multi-particle model and hybrid optimization strategy is established. Based on the line design parameters, the technical parameters of the new EMU are combined. The train running simulation based on the route design scheme is completed, and the V-S curve is drawn, which provides the necessary conditions for introducing the train operation simulation results into the vehicle line dynamics model. (2) drawing lessons from the existing vehicle line dynamics research results, The vehicle line dynamics model oriented to the route design scheme is established. In the course of modeling, the line alignment condition is fully considered, and the simulation results of the above train operation are combined with the above mentioned train operation simulation results. The dynamic response analysis of the railway line is realized. (3) the research method of line comfort degree is put forward by introducing the train operation simulation principle into the existing train line dynamics theory. The line scheme is divided into several evaluation sections according to the line shape of horizontal and longitudinal plane. According to the criterion, the spectrum analysis of lateral and vertical vibration acceleration is completed in each evaluation section and the stationary index value is solved. Based on the principle of optimal matching between vehicle and line, the conclusion of comfort evaluation is applied to the link of line design and auxiliary route design. (4) the evaluation system of comfort degree for high-speed railway line design scheme is developed. The above system is completed by using the CAD secondary development tool ObjectARX2006 and Matlab Math Library function library under the environment of VS.NET, and the rationality and practicability of the program are verified by an engineering example.
