Hydraulic Integrated Interconnected Regenerative Suspension: Sensitivity Analysis and Parameter Optimization

Hydraulic integrated interconnected regenerative suspension (HIIRS) is a novel system that can simultaneously harvest the vibration energy in and enhance vehicle dynamics. The parameter sensitivity of HIIRS analyzed significant parameters are optimized this paper. Specifically, half-vehicle model with established. Based on model, hydraulic three objectives, ride comfort, road holding, average harvesting power. considered study more abundant than those previous related studies, including cylinder inner diameter, motor displacement, resistance, initial pressure, accumulator parameters. It turns out most sensitive diameter cylinder, displacement motor. To further performances could present, both single-objective optimization multi-objective problems solved compared traditional suspensions. performs better comfort holding anti-roll bar suspension. Different from design, not only considers performance but also incorporates characteristics into objective. In optimization, Pareto front obtained, which shows conflicts power, while power did conflict. superior to harvests considerable energy.
