Stability analysis of skyhook damper suspension system with time delay for high-speed railway vehicle
A 1/4 car model of railway vehicle including primary suspension is built up. Effects of time delay on system dynamic performances are analyzed. According to the theory of critical instability, the value of the critical time delay for high-speed EMU at 300km/h is computed and the stability in different time delay area is analyzed. Effects of time delay on frequency response are analyzed on the basis of transfer properties of systems. Simulation analysis on the vibration of car body under deterministic excitation and track irregularity random excitation is conducted. Frequency response analysis and simulation results prove that the analysis of the critical time delay of system instability based on time delay theory is right.
