随着地铁列车的发展,车辆的速度不断提升,客室内部空间不断要求加大,为满足高速转向架1、2系悬挂装置空间的需求,保证客室地板高度的统一及底架结构的延续,减薄地板结构成为一项新的课题。泡沫铝地板是一种新型薄地板,具有良好的隔声和减震性能。文章研究该新型地板能否满足城轨地铁车辆运营及反复的载荷变化要求,进行相关测试。
With the development of subway trains, the speed of vehicles continues to increase, the interior space of passenger cabins continues to increase. In order to meet the demand of high-speed bogies 1 and 2 suspension systems, the unification of the floor height of the passenger cabinets and the continuation of the chassis structure, Thin floor structure has become a new topic. Foam aluminum floor is a new type of thin floor, with good sound insulation and damping properties. The article studies whether the new floor can meet the requirements of urban rail transit vehicle operation and repeated load changes, and carry out related tests.
