Experimental investigation of friction noise in lead screw system under mode-coupling

Sound quality analysis of slide adjuster for automotive power seat using stepwise regression

“…Therefore, researches are continuously focused on reducing the level of driving noise. However, low frequency noises (such as amplitude modulation) and the high frequency noise (such as friction) have such a negative effect on the driver that even if the level is low, that there is a limit to improving the emotional quality by noise reduction [5]. Previous studies on seat noise have been performed in a variety of ways, including structural resonance, squealing, noise source investigation, and sound quality assessment of the operating noise of the seat adjuster, etc.…”

“…Previous studies on seat noise have been performed in a variety of ways, including structural resonance, squealing, noise source investigation, and sound quality assessment of the operating noise of the seat adjuster, etc. [6][7][8][9]. In other words, studies on the mechanism noise of power seats have been aimed at identifying the cause of the specific noise, evaluating the operation sound quality, and constructing the sound quality model using statistical analysis [10].…”

A Study on the Experimental Analysis of Noise from Vehicle Power Seat Slide Rail

“…Among them, the seat is a core module encountered first by the passenger, and requires to deep reflection of ergonomics and sensitivity engineering such as vibration and shock absorption, sitting postural control function to maintain amenity different from a general seat. In particular, consumers" complaints caused by operating noise produced by the slide mechanism in the power seat have an increasing trend [3,4], in order to solve this problem, it is necessary to analyze the vibration characteristics of the seat mechanism [5,6]. Since the slide mechanism in the power seat is driven by a small DC motor [7], and the noise produced thereby occurs in combination from diversified noise sources such as ball bearing, reduction gear, shaft alignment, lead screw and nut, motor rotation, resonance, shock, friction, etc., there is considerable difficulty in noise analysis [8].…”

The Noise Characteristics of Reduction Gear for Moving Device of Automotive Seat

“…Automotive seat is equipped with various convenient components such as slide mechanism, recliner, height, lumbar support, tilt, and most of them are controlled by electric motor [3]. Among these components, the slide mechanism is a device that moves seat back and forth.…”
