摘要： A method of determining steering rack rattle propensity of a rack and pinion steering assembly may comprise: simultaneously recording audio, and measuring acceleration of a rack, and right and left side tie-rod end loads; identifying rack rattle events from the audio recording; determining common characteristics of the measured rack acceleration and tie-rod end loads during the identified rack rattle events; creating a rack rattle index level; applying a predetermined force profile to a test rack and pinion steering assembly; measuring a test acceleration on the test rack and pinion steering assembly; calculating a test RMS level in a test frequency range using a test time constant; determining a rack rattle index value from the calculated test RMS level; and comparing the rack rattle index value to the rack rattle index level.

摘要： A pressure relief valve for relieving air pressure from an automotive vehicle interior. The pressure relief valve mounts on a valve mounting location that surrounds a body opening and includes flexible interleaved flaps and a securing mechanism. The flaps cover the body opening, with each of the flaps being generally triangular in shape and having an outer end adjacent to the valve mounting location and a pair of sides extending from the outer end inward to an inner corner, with the inner corners meeting to form a peak. The interleaved flaps form a generally pyramidal-shape that angles away from the automotive vehicle interior as the interleaved flaps extend inward from the outer ends toward the peak. The securing mechanism is secured to the radially outer ends of the flaps and to the valve mounting location.
