铁道车辆转向架摇动台悬挂系统横向刚度研究

在转向架的发展过程中,为了改善铁道车辆的动力学性能,提出摇动台式二系悬挂系统,其由摇枕、螺旋压缩圆弹簧、弹簧托盘和吊杆组成。文章基于摇动台结构的工作原理,导出摇动台系统的横向刚度计算方法,为此类转向架改进设计提供理论基础。

The Needed Minimum Submergence Depth When a Submarine Runs into Typhoon

In this paper, the influence depths of all levels of wind power produced waves are reckoned according to the measured swaying degree when a submarine meets with a force 11 strong tropical storm and has to submerge; Then the minimum submergence depth is given when a submarine is faced with weather systems with force ≥ 6 wind and the swaying degree of less than 12 degree is assured as reference for a submarine working and sailing in big strong winds and waves.
