高速动力车转向架二系悬挂高圆簧配置选择

THE CHOICE OF ARRANGEMENT FOR SECONDARY SUSPENSION FLEX-COIL SPRING OF HIGH-SPEED POWERING BOGIE

本文主要论述我国高速动力车转向架二系悬挂高圆簧的配置选择，在保证二系悬挂性能指标的基础上，提出了每台转向架布置六组高圆簧的方案，并将该方案与德国ＩＣＥ高速列车驱动转向架二系悬挂高圆簧布置方案进行了分析比较，证实了ＩＣＥ驱动转向架二系悬挂高圆簧的布置方案和结构设计是合理的。六组与四组高圆簧方案各有优缺点，在我国高速动力车转向架二系悬挂设计中，仍采用每台转向架布置四组高圆簧方案为宜。

This thesis describes the choice of arrangement for secondary suspension flex-coil spring of high speed powering bogie in our country. The plan of the arrangement of six flex-coil springs for each bogie has been optimized on the basis of the specifications of the secondary suspension flexcoil springs. In addition,the comparsoin between this plan and that ofICE of Germany has been made in detail.and It is concluded that the latter is more better.Inthe design of the high speed powering bogie in our country,the arrangement of four flex-coil springs for each bogie has been adopted.
