双层客车横向动力性能的研究

作者根据我国新双层客车的结构特点，建立了横向动力性能的数学模型，校核了车体在弹簧上的倾覆稳定性，分析了车辆以不同速度通过道岔及渡线时的车体横向移动量、脱轨系数和轮重减载率。同时还估测了在线路不平顺的激扰下双层客车的随机响应。计算结果表明，新双层客车不仅满足运行安全的要求，而且具有良好的平稳性能。

Virtual prototype simulation on underwater hydraulic impingement shovel

The virtual prototype technology is applied to the design of the hydraulic impingement shovel, which is to increase the reliability of the design. The work principle of hydraulic impingement shovel is expatiated, and its dynamic equations are established. The 3D model of virtual prototype is built by PRO/E. Then the couple between the mechanical body of prototype and the hydraulic system is completed by virtue of ADAMS. Finally, the simulation is made on the virtual prototype. The simulation results show that the design of underwater hydraulic impingement shovel is rational. The virtual prototype technology could lay sound foundation of successful manufacturing of physical prototype for the first time and offer highly effective and feasible means for the design and production of underwater equipments.
