摘要
本文通过对现有干线客车车体钢结构的试验模态分析,预测准高速客车车体的动态特性;并就车体轻量化以及改善车体动态特性提出看法。
On the basis of the test modal analys's of thecarbody steel structure of main line passenger cars,the dynamic characteristics of quasi-high speed pas-senger carbodies are predicted, and new ideas concern-ing the carbody weight lightening and improvementsof carbody dynamic characteristics are put forward.
