Abstract
A method at power steering hose assembly design and analysis for a power steering system in a vehicle includes the steps of selecting a mesh model of a design for a power steering system having a power steering hose assembly, selecting a predetermined characteristic of the power steering system for a predetermined operating condition, performing an acoustic analysis on the mesh mocel using the predetermined characteristic and determining an acoustic response cf the power steering hose assembly from the acoustic analysis. The method further includes the steps of determining a noise transmission loss across the power steering hose assembly using the acoustic response, determining whether the transmission loss meets a predetermined noise criteria and modifying a design parameter for the power steering system if the transmission loss does not meet a predetermine noise criteria.
