【摘要】 通过试验室的静、动力试验，确定了弹条Ⅰ型扣件的纵向、竖向及横向的三维动力特性；为研究列车三向激励下，车—道系统、道—桥系统及车—道—桥系统的结构响应提供了有参考价值的静、动力参数更多还原

【Abstract】 By static and dynamic tests in laboratory, spring Ⅰ type fastener three dimensional dynamic properties in the longitudinal, vertical and transversal directions are determined. Static and dynamic parameters with reference value are provided in this paper for studying structural response of train track system, track bridge system and train track bridge systems under train three dimensional excitation.更多还原
