摘要
分析了国内外机车车体和转向架模态分析的现状,对其中存在的问题和评价方法存在的差异进行了分析,以现有的车体和转向架为例,对其在整备状态下的模态进行分析,其中重点研究在对车体和转向架进行模态分析时模型的建立问题。通过对采用不同的分析模型所得到的模态分析结果进行比较,提出了对车体和转向架模态分析有关模型的处理及评判的结论和建议。
The paper analyzed the present situation of model analysis of carbody and bogie of locomotive,discussed the existential questions in model analysis and the discrepancy in its assessment method,and took the assessment method from foreign company as a reference.On this basis,it provided an example of the present carbody and bogie and carried out the model analysis under supplied condition in which it put emphasis on the research of modeling.By comparing the results of different used analysis models,conclusion and suggestion were made on dealing with and assessment of related models about model analysis of carbody and bogie.
