Hydraulic Power Steering System Design and Optimization Simulation 2001-01-0479

Hydraulic rack and pinion power steering system is a high bandwidth servo with stringent performance requirements on accuracy, reliability, and cost. Design of such a system can be best achieved by using a validated and user friendly computer simulation program. Hydraulic integrated power steering ( HIPS ) program has been developed using basic concepts from science and engineering. HIPS provides a design and test environment for the integrated steering and suspension system subjected to disturbance forces, which may be induced by pump flow oscillations and tire loads. Two real-world automotive hydraulic steering systems are simulated with HIPS. The simulation results agree closely with the dynamometer test results. The application of HIPS for design optimization is also demonstrated.
