Multi-dimensional vibration reduction and isolation double-block type ballastless track
The invention discloses a multi-dimensional vibration reduction and isolation double-block type ballastless track. The track comprises a roadbed slab; the first sleeper and the second sleeper are respectively arranged on the top side of the roadbed slab and are oppositely arranged; the truss comprises a plurality of first connecting rod structures and a plurality of second connecting rod structures, the two ends of each first connecting rod structure are embedded in the first sleeper and the second sleeper respectively, and each first connecting rod structure comprises at least two main sections and an inerter vibration reduction system connected between the adjacent main sections; the two main sections located on the outermost side are connected with the first sleeper and the second sleeper in a one-to-one correspondence mode. A second connecting rod structure is connected between any two adjacent first connecting rod structures, each second connecting rod structure comprises at least two auxiliary sections and an inerter vibration reduction system connected between the adjacent auxiliary sections, and the two auxiliary sections located on the outermost side are connected with the two adjacent first connecting rod structures in a one-to-one correspondence mode. The multiple inerter vibration reduction systems on the truss can accelerate and consume vehicle-induced vibration in multiple directions, and therefore multi-dimensional vibration reduction is achieved.
本发明公开了一种多维减隔振的双块式无砟轨道，包括：道床板；第一轨枕及第二轨枕，分别设于道床板顶侧并相对设置；桁架，包括多个第一连杆结构及多个第二连杆结构，各第一连杆结构的两端分别埋设于第一轨枕及第二轨枕内，第一连杆结构包括至少两个主节段及连接于各相邻的主节段之间的惯容减振系统，位于最外侧的两个主节段分别与第一轨枕及第二轨枕一一对应连接；任意两个相邻的第一连杆结构之间连接有第二连杆结构，其包括至少两个副节段及连接于各相邻的副节段之间的惯容减振系统，位于最外侧的两个副节段分别与两相邻的第一连杆结构一一对应连接。在本发明中桁架上的多个惯容减振系统可以将多个方向的车致振动加速消耗，从而实现多维减振。
