Patent ID: 6917907

Claim:
A method of power steering hose assembly design and analysis for a power steering system in a vehicle, said method comprising the steps of: obtaining a design for the power steering system from a database stored in a memory of a computer system, wherein the power steering system includes a power steering hose assembly having a noise attenuation device; selecting a mesh model of the power steering hose assembly from the power steering hose assembly design; obtaining a predetermined characteristic of the power steering system for a predetermined operating condition of the vehicle; performing an acoustic analysis on the mesh model of the power steering hose assembly using the predetermined characteristic; determining an acoustic response of the power steering hose assembly from the acoustic analysis; 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; modifying a design parameter for the power steering system if the transmission loss does not meet the predetermined noise criteria; and using the power steering hose assembly design and analysis if the transmission loss does meet the predetermined noise criteria.
