摘　　要：灰色理论应用于转向架质量评估,提出了灰关联分析方法,建立转向架质量影响因素的模型,度量因素之间的关联度,再由关联度导出灰色关联序,最终评估出转向架质量各影响因素对转向架质量的主次影响程度。以重车心盘载荷为转向架生产质量参数,分析得出弹性旁承预压缩量、旁承弹性体垂向刚度和车体自重对转向架生产质量影响依次降低。成功针对模糊性事件通过灰色理论挖掘出了未知信息,并对各因素影响程度进行了排序,分出主次,方法可行有效,具有较好的推广性。The grey theory is applied to the bogie quality evaluation. Grey relational analysis method is pro- posed. Bogie quality influence factors model is set up. Measure of the correla.tion between factors and then export grey relational sequence by correlation. Ultimately assess bogie quality factors on the quality of the bogie primary and secondary influence degree. Regrad the center plate load in heavy truck as bogie production quality parameters. Through analyzing, the influence of bogie production quality in turn reduce is elastic precompression of side bearings, side bearing elastomer vertical stiffness and body weight. Success in view of the fuzziness event were dug up by grey theory unknown information. And sort the incidence, take stress, and the method is feasible and effective, has the good extension.
