Abstract: A track vibration damping rubber pad was prepared by adding carbon black, white carbon
black, clay, and calcium carbonate with different particle sizes as fillers to ethylene propylene rubber. The
influence of different fillers and particle sizes on the dynamic and static stiffness ratio of the pad was studied.
The results showed that the dynamic to static stiffness ratio decreased with increasing particle size when using
carbon black, increased with increasing particle size when using white carbon black, and varied irregularly
and minimally with increasing particle size when using clay and calcium carbonate. Meanwhile, when using
reinforcing fillers such as carbon black and white carbon black, the dynamic and static stiffness of the pad is
higher than when using filling fillers.
Key words: fillers; particle size; dynamic static stiffness ratio; ethylene propylene rubber; track vibration

27 亿元轮胎项目，正式公示！
The 2.7 billion yuan tire project has been officially announced!

2024 年 11 月 13 日，高性能绿色摩托车子午线轮胎智能制造项目，进行公示。据了解，该项目由腾森橡胶
2
轮胎（威海）有限公司建设，总投资 27 亿元。建设地点位于威海市经济技术开发区，占地面积 22.44 万 m 。
建成后，可年产高性能绿色摩托车子午线轮胎 1 200 万套。腾森橡胶成立于 2006 年，是一家集摩托车轮胎
和丁基内胎研发、制造、销售为一体的标准化、专业化、现代化轮胎制造商。该公司目前产品包括丁基内胎、摩
托车外胎，2023 年丁基内胎产量 700 万条，摩托车外胎产量 750 万条。
该公司提到，目前，高性能绿色摩托车子午线轮胎在国内内资企业中还处于起步阶段，与世界先进水平差距
较大，国际高性能绿色摩托车子午线轮胎市场被国外巨头垄断。
调整摩托车轮胎的产品结构，提升产品档次和水平，提高国际市场的竞争能力，是我国摩托车轮胎行业的当
务之急。该项目投产后，将实现高性能绿色摩托车子午线轮胎的国产化替代，弥补行业的技术空白，产品综合性
能达到国际先进，有利于促进我国摩托车胎行业产品结构调整和技术进步，推动我国高性能绿色摩托车子午线轮
胎技术发展与国际接轨，为我国摩托车产业和摩托车轮胎产业高质量发展提供有力支撑。
