利物浦大学最近进行的一项研究表明，即使在相同的制动系统下，在相同的压力下，两组新衬垫的静态接触压力分布也会发生变化。这种变化的一个可能的原因是由于刹车片表面地形。研究了刹车片形貌对接触压力分布的影响。Pressurex®，压力指示膜用于测量静态接触压力分布。建立了考虑垫面轮廓的盘式制动器三维有限元模型。用线规测量刹车片的地形。本研究研究了六种不同的衬垫结构。调查结果可以更好地解释接触压力分布的变化，进而解释尖叫的产生。
Recent studies carried out at the University of Liverpool showed that there was a variation in static contact pressure distributions on two new sets of pads even though they were tested with the same brake system under the same pressure. One of the possible reasons for this variation is due to brake pad surface topography. This paper investigates the effects of brake pad topography on contact pressure distributions. Pressurex ® , pressure indicating films are used to measure static contact pressure distribution. A detailed 3-D finite element model of a disc brake is also developed and takes into account pad surface profiles. A linear gauge is used to measure brake pad topography. Six different pad configurations are studied in this investigation. Results from the investigation could provide a better explanation of the variation in contact pressure distribution and in turn squeal generation.
