摘要:简要介绍了国外现有的变轨距转向架的运用与发展现状,根据我国国情,提出了一种新型的变轨距转向 架方案.文中对总体结构进行了简要说明,并利用数值模拟方法对变轨距转向架的动力学性能进行了详细的分 析研究.结果表明,变轨距转向架的结构方案是可行的,具有较好的抗蛇行稳定性和平稳性,曲线通过性能有待 于进一步完善.Abstract:Application and development of gauge-changeable bogies abroad are briefly introduced. According to the situation in China, a new scheme for gauge-changeable bogies was proposed, its structure was presented, and its dynamic performances were analyzed with numerical simulation. The results show that the proposed scheme is basically feasible, with good hunting stability and riding quality, except that the curving performance needs to be improved.
