Advanced Modeling and Stability Analysis of Electro-Hydraulic Control Modules for Intelligent Chassis Systems

• A comprehensive nonlinear model of electro-hydraulic power-shift systems incorporating pipeline characteristics was developed and validated experimentally, showing high accuracy. • The model including pipeline parameters aligns more closely with experimental data than models without, highlighting the importance of pipeline effects. • Damping coefficient, feedback cavity orifice diameter, and pipeline length critically affect system stability, while spring stiffness has minimal impact. • The findings provide practical insights for optimizing electro-hydraulic control modules in intelligent chassis systems for automotive and construction machinery.
