METHOD TO IMPROVE THE NOISE GENERATED BY THE ROLLING BELT OF A TIRE BY RELATIVE ROTATION OF A NERVE, AND TO SIMULATE THE ROLLING BAND NOISE EFFECTED IN THIS WAY.

摘要

A METHOD IS ESTABLISHED TO EVALUATE THE UNPLEASANT NOISE LEVEL ASSOCIATED WITH THE OPERATION OF A TIRE UNDER ITS BEARING ON CONTACT WITH A ROLLING SURFACE, WHICH INCLUDES DIGITIZING THE ROLLING DESIGN IN A COORDINATED CONTROL SYSTEM FOR A COORDINATED SYSTEM THE BEARING IN CONTACT WITH THE FLOOR AND DIFFERENTLY DISTINGUISHES THEM FROM THOSE PORTIONS OF THE BEARING THAT ARE NOT IN CONTACT, AS MULTIPLE MATRIX ELEMENTS; DEFINE A GENERALLY CURVED PROFILE OF A STEERING EDGE AND TRAILER TO GIVE AN EQUATION TO THE EDGE; PERFORMING THE UNITED SUM OF TIME, OF THE NOISE PRODUCED BY EACH MATRIX ELEMENT, ON EACH ONE OF THE MATRIX ELEMENTS IN THE TOTAL CIRCUMFERENTIAL SURFACE; CONVERT THE SUMA SEQUENCE INTO A PERIODIC ANALOG SIGNAL; CONVERT THE ANALOG SIGNAL INTO SOUND AND ORALLY ASSESS THE SOUND. IN A SIMPLIFIED CASE OF 0.5 AND 1.5 ALONG AT LEAST ONE SEDIMENT MOLD EDGE ARE MEASURED SEQUENTIALLY AROUND THE TIRE CIRCUMFERENCE. THE SYSTEM REQUIRES ONLY SOME MEANS TO DIGITIZE THE BEARING MODEL, A COMPUTER TO PERFORM THE NECESSARY DATA HANDLING, AND SOME MEANS TO CONVERT A DIGITAL SIGNAL INTO AN ANALOGED SIGNAL, SUBJECTIVELY RENOVATED, A RENOVATED MODEL. THE RIBS ARE THEN ROTATED RELATIVELY ONE WITH RESPECT TO THE OTHER TO OBTAIN AN IMPROVED LEVEL OF BEARING NOISE.
