摘要
依据TB/T 1718-2003标准中轮轴过盈量的规定,对CRH380BL动车组新车轮与磨耗车轮进行了过盈配合强度评价;在考虑轮轴过盈量下,依据UIC 510-5-2003标准确定了新车轮与磨耗车轮的载荷工况及载荷大小,分别在直线工况、曲线工况及道岔工况下对其进行静强度评价。分析结果表明:按照相关标准,CRH380BL动车组车轮过盈配合强度及静强度均满足设计要求。
According to the provisions of the axle interference amount in TB/T 1718-2003,the interference fit strength of the new and worn wheels in CRH380 BL EMU is evaluated;With the consideration of wheel-axle interferences,the loading conditions and loading sizes of new and worn wheels are determined according to UIC 510-5-2003 standard.And the static strength evaluation is carried out in linear condition,curve condition and turnout condition.The analysis results show that the interference fit strength and static strength of CRH380 BL EMU wheels can meet the design requirements according to the relevant standards.
