摘要
文章认为,高速车轮应当具有与高速动车组使用条件相匹配的高洁净度、高强韧配合特点及材料特性,我国已具备进行高速车轮自主创新的条件和基础,应将其纳入高速动车组自主创新体系,按系统性、先进性、实用性的原则扎实推进,在2至3年内实现200km/h～250km/h高速车轮的自主创新、装车使用,4至5年内实现350km/h及以上高速车轮的自主创新、装车使用。
The wheels for high speed cars should have the features of fine cleanliness,rational match of high strength and toughness and proper material properties which suit for the service conditions of high speed multiple units.The conditions and foundation for independent innovation of wheels for high speed cars in china are ready,and should be included in the independent innovation system of high speed multiple units.The innovation shall be carried out according to the principles of systematicness,advancement and practicability.The independent innovation and on-line service of wheels for 200～250 km/h cars will be realized within 2~3 years and those for 350 km/h or above will be realized within 4～5 years.
