MAGNETO-RHEOLOGICAL FLUID-BASED RECIRCULATING BALL ELECTRO-HYDRAULIC STEERING SYSTEM AND OPTIMIZATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/134622
Kind Code:
A1
Abstract:
A magneto-rheological fluid-based recirculating ball electro-hydraulic steering system and an optimization method therefor. Said system comprises: a mechanical transmission module, an electric power assist module, a magneto-rheological fluid power assist module, and a power assist control module (ECU); magneto-rheological fluid materials (25) are provided in magneto-rheological fluid cavities (24) in a recirculating ball steering gear (7); excitation coils (8) are provided outside a recirculating ball steering gear housing (18); and the direction of the magnetic field generated by energizing the excitation coils (8) is perpendicular to the direction of the electric field formed by energizing electrode plates (12). By establishing an electro-hydraulic steering system optimization model and performing optimization using a niche multi-target particle swarm optimization algorithm, the structure of said system is simplified and the controllability of steering feel is improved.
