Title:
METHOD AND DEVICE FOR ANALYZING VIBRATION NOISE REDUCTION IN AUTOMOTIVE PANEL PART
Document Type and Number:
WIPO Patent Application WO/2021/053872
Kind Code:
A1
Abstract:
A method for analyzing vibration noise reduction in an automotive panel part according to the present invention includes: a step S1 for acquiring a vehicle body analysis model 41 having a floor panel model 43; a step S3 for setting analysis conditions relating to a bead variable distribution which is applied to the floor panel model 43; a step S5 for setting one area in which beads are to be provided; a step S7 for acquiring a bead variable distribution which is applied to the bead provision area; a step S9 for reacquiring the equivalent radiation power (ERP) of the floor panel model 43 to which the acquired bead variable distribution has been applied; a step S11 for obtaining a bead variable distribution with which ERP is minimized in the bead provision area; and a step S13 for determining the bead variable distribution with which ERP is minimized as the optimum distribution of bead that are to be provided to a floor panel 31.
