CAR Body Self-Vibration Control And Optimization

As the railway rolling stock improvement of speed , the vibration of the car body become acute , and the passenger will feel tired to take for a long time in the carriage shaking, the violent vibration of vehicle can damage the vehicle structure too, effort between a rail and vehicle vibration will also influence the traffic safety after reaching a certain degree. Control vehicle vibration whether rolling stock raise speed and improve key technology of stationarity their one of. Rolling stock dynamics , vibration and multi-disciplinary research of running side by side of control are the front subject of solving the vehicle vibration problem at present.For this reason the country has build 863 subject, "basis on designing the complicated fictitious technical research of prototype of a machine of products with cocurrent engineering in coordination". As a part of the subject, this text has used three kind of software, ADAMS, Matlab and Isihgt, while the text make full use of the virtue of these software and build PID control system to solve the problem. Also it optimizes the PID parameter and achieve good result.
