Zhuhai Glory Friction Material Co., Ltd was established in Nov. 11, 2002. With years of development, we have become a professional friction material enterprise integrating manufacturing, production, sales, research and development, and service. And it has successfully entered into international supporting system and supplied OE products for ZF-TRW and Continental.
In 2012, ZHUHAI Glory friction materials co., ltd. was recognized as a national high-tech enterprise, and in 2015, Glory friction materials research and development center was rated as Guangdong engineering technology center. So far, Glory has 3 manufacturing enterprises, 4 research and development centers, 1 service enterprise, 1 management school and 1 trading enterprise, with a total staff of nearly 1,000 and a total assets of more than 400 million RMB.
As a professional auto supporting manufacturers in the industry, Glory independently develops and produces disc brake pads, drum brake shoes and other brake products and accessories. With excellent performance, stable quality and comprehensive model coverage, Glory has become one of the benchmark in the automotive friction material industry in China. Since 2014, Glory has been officially supporting the international high-end brake factory, such as: Great Wall, CHANA, SGMW such as more than 20 vehicle enterprises and ZF-TRW, CTCS, Continental, Huacheng brake, Bethel, Wanxiang Group, And so on automobile safety system manufacture enterprise, enjoys the reputation in the domestic and foreign automobile parts market.
In order to achieve long-term development and sustainable management, Glory is expanding the connotation of business: customer-centric, technology research and development based, pay attention to production services, communication and collaboration, integration of social resources, introduction of professional software, and strive to become a world-class modern enterprise.

Low frequent system excitation (Creep Groan) is a complaint from customers for a long time. Former research shows that this issue is system-related, and it is also considered that the friction characteristic of the friction couple under the condition of low pressure and low sliding speed is the source of the low-frequency vibration.
A methodology is developing to study and qualifying the friction behaviour under the condition of extremely low sliding speed by use of scale dynamometer. This paper attempts to obtain the torque variation and measure the static and dynamic torque and analysis of its continuously conversion process and trying to find the cause of low frequency excitation (Creep Groan) in the aspect of friction materials.
As the first step, this paper introduces the consideration of the methodology development and the preliminary analysis of the test data. Also, in terms of a methodology, the repeatability is essential and analysed in chapter 3. Furthermore the paper describes the correlation between the stick-slip test and the vehicle slope test. The five quantify parameters used for represented stick-slip characteristic are highly negative correlated with the vehicle slope test results.
