With the development of high-speed railways, passive suspension systems struggle to adapt to complex working conditions. This paper focuses on the research of semi-active control strategies for secondary lateral suspension to improve vehicle ride comfort and operational stability. A co-simulation platform combining SIMPACK and MATLAB/SIMULINK is established, and traditional damping control strategies (skyhook, acceleration damping) and fuzzy control strategies are proposed and verified. The results show that the fuzzy skyhook hybrid control strategy effectively balances the vibration of the car body and bogie frame. Its control effect is close to that of continuous skyhook damping, while offering lower costs.

摘要

With the development of high-speed railways, passive suspension systems struggle to adapt to complex working conditions. This paper focuses on the research of semi-active control strategies for secondary lateral suspension to improve vehicle ride comfort and operational stability. A co-simulation platform combining SIMPACK and MATLAB/SIMULINK is established, and traditional damping control strategies (skyhook, acceleration damping) and fuzzy control strategies are proposed and verified. The results show that the fuzzy skyhook hybrid control strategy effectively balances the vibration of the car body and bogie frame. Its control effect is close to that of continuous skyhook damping, while offering lower costs.
