Description

technical field [0001] The invention relates to related engineering technical fields such as railway engineering vibration suppression, and specifically relates to an active-passive composite control system for suppressing roll, nod, and head-shaking behaviors of high-speed trains. Background technique [0002] The high-speed railway runs fast, and its dynamic behavior is complex. During the operation, it may suffer from the dynamic behavior of track irregularities, air pressure differences between trains, and external factors such as wind, rain, and snow. It is no longer a single motion mode control problem, but It is a complex problem involving the translational motion of the car body (heavy, yaw, and expansion), the rocking motion (nodding, shaking the head, and rolling) and its coupling vibration and motion. It is important to study the control system suitable for solving the complex dynamic behavior of the train. Theoretical and practical significance. [0003] Aiming ...

AI Technical Summary

Problems solved by technology

[0009] The main purpose of the present invention is to provide an active-passive composite control system that suppresses roll, nod, and head-shaking behaviors of high-speed trains, so as to solve the high-speed train's motion forms with rotational components such as head-shaking, side-rolling, and nodding that exist in the prior art , relying solely on the linear force provided by the existing suspension system cannot form the most effective control force, which makes the control function of the existing suspension system unable to be fully utilized, and the unfavorable dynamic response of the train cannot be fully suppressed. Problems such as head shaking, rolling, and nodding of high-speed trains cannot be effectively suppressed, and the train’s operating conditions are poor.
