Efficiency Analysis of Hydraulic Power Steering System

چکیده
Hydraulic assisted 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 realworld 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.

Nearly all tractor PTO arrangements used today consist of a rotating mechanical shaft with two or more universal joints. This arrangement continues to be an entanglement hazard. By driving the attachment with fluid power, this hazard could be eliminated. This project included the design, development, and testing of an experimental tractor based on a John Deere 4040. The entire power train was t...
