被动式动力减振的梯形轨枕轨道结构
摘要：
被动式动力减振的梯形轨枕轨道结构，以降低与轨道结构固有频率接近的振动成份，消除轨道结构在该频段的有害振动。包括设置于支撑基础（106）之上的一对横向间隔的纵向梯形轨枕（101），该对梯形轨枕（101）由沿线路延伸方向间隔设置的连接构件（102）连接为一体，钢轨（104）通过扣件（105）固定于梯形轨枕（101）上，其特征在于：所述梯形轨枕（101）上或支撑基础（106）上沿线路延伸方向间隔设置有附加质量块（103），附加质量块（103）通过弹性构件与梯形轨枕（101）或支撑基础（106）弹性连接。以降低与轨道结构固有频率接近的振动成份，消除轨道结构在该频段的有害振动。
摘要（英）：

A trapezoid sleeper rail structure for passive dynamic vibration reduction aims to reduce vibration components with the frequency close to the inherent frequency of a rail structure so as to eliminate harmful vibration of the rail structure at the frequency band. The trapezoid sleeper rail structure comprises a pair of longitudinal trapezoid sleepers (101) arranged on a supporting foundation (106) and transversely spaced, the trapezoid sleepers (101) are connected as a whole through connecting components (102) arranged at intervals in the extending direction of a line, and steel rails (104) are fixed to the trapezoid sleepers (101) through buckles (105). The trapezoid sleeper rail structure is characterized in that added mass blocks (103) are arranged at intervals on the trapezoid sleepers (101) or on the supporting foundation (106) in the extending direction of the line, and the added mass blocks (103) are connected with the trapezoid sleepers (101) or the supporting foundation (106) in an elastic mode through elastic components. The trapezoid sleeper rail structure for passive dynamic vibration reduction aims to reduce the vibration components with the frequency close to the inherent frequency of the rail structure so as to eliminate harmful vibration of the rail structure at the frequency band.
