Floating slab track capable of self-adjusting inherent frequency
The invention provides a floating slab track capable of performing inherent frequency self-adjustment. The floating slab track comprises a sensing optical cable, a steel rail, a fastener, a roadbed slab, a rigidity non-adjustable vibration isolator, a rigidity adjustable vibration isolator and a single chip microcomputer. The roadbed slab is installed on base concrete, and grooves are formed in the two sides of the roadbed slab and used for containing the rigidity-non-adjustable vibration isolator and the rigidity-adjustable vibration isolator. The vibration isolators are arranged in pairs, a steel rail is installed on the tops of the two vibration isolators through fasteners, and a sensing optical cable and an array grating sensor are further connected to the roadbed slab. The fundamental frequency of the floating slab track can be adjusted according to the vibration response data, collected by the array grating sensor in real time, of the floating slab track bed, the deviation between the fundamental frequency of the floating slab track and the designed fundamental frequency is controlled within a proper range through the rigidity-adjustable vibration isolator, and therefore the stability of the service performance of the floating slab track is ensured.
本发明提供一种可进行固有频率自调节的浮置板轨道,包括传感光缆、钢轨、扣件、道床板、刚度不可调隔振器、刚度可调隔振器、单片机;道床板安装于基底混凝土上,道床板两侧开槽用于放置刚度不可调隔振器和刚度可调隔振器;隔振器成对设置,两个隔振器顶部通过扣件安装有钢轨,道床板上还连接有传感光缆和阵列光栅传感器。本发明的浮置板轨道的基频可以根据阵列光栅传感器实时采集的浮置板道床的振动响应数据进行调节,通过刚度可调隔振器将浮置板轨道的基频与设计基频偏差控制在合适的范围内,从而确保浮置板轨道服役性能的稳定性。
