轨道用聚氨酯新品的开发和应用

Development and application of new polyurethane products for railway

从目前国际上最前沿的研发思路和科研成果着手,介绍新型轨枕材料的优点和应用的益处,给铁路行业一点启示,希望能够走出目前广泛使用但显得较为陈旧的混凝土结构的枕木思路圈,使我国未来使用的轨道枕木能真正满足高速、重载、减振、降噪、长寿命、环境友好的要求。

This paper introduces the advantage of new material for the rail sleeper and the benefit from its application through presenting the most cutting-edge research ideas and results in the world. We hope it can inspire the railway industry and make us get out of the train of thought sticking to the old concrete structure of the sleepers which are widely used now, And let the rail sleeper in the future can really meet the requirements of high-speed, heavy duty, vibration attenuation, noise reduction, long life, environment friendly.
