Study on Dynamical Simulation of Railway Vehicle Bogie Parameters Test-Bench Electro-Hydraulic Servo System

Abstract:

Dynamical mathematical model was established for accurately positioning, fast response and real-time tracing of electro-hydraulic servo control system in railway vehicle bogie parameters test system with elastic load. The model could precisely control the output of position and force of the hydraulic cylinders. Induction methods was proposed in the paper. Dynamical simulation verified the mathematical model by software simulink. Meanwhile the key factors affecting the dynamical characteristics of the system were discussed in detail. Through the simulation results, high precision is obtained in application and the need of real-time control on the railway vehicle bogie parameters test-bench is realized .
