Abstract

The invention discloses a floating slab track, a vibration control method thereof and a device. The vibration control method of the floating slab track includes the steps: acquiring vibration direction of the floating slab track; controlling damping force opposite to the vibration direction generated by a magnetorheological damper according to the vibration direction, and deploying the magnetorheological damper on the floating slab track; building a kinetic model according to the damping force and structure parameters of the floating slab track; performing vibration reduction for the floating slab track according to the kinetic model. A control strategy is added based on the magnetorheological damper and controls the magnetorheological damper to generate the damping force opposite to the vibration direction according to the vibration direction. According to the floating slab track, low-frequency vibration reduction response of the floating slab track is effectively restrained.

Description

technical field [0001] The invention relates to the field of tracks, in particular to a floating plate track and a vibration control method and device thereof. Background technique [0002] At present, with the rapid development of urban traffic, the problem of vibration and noise is becoming more and more serious. Because the vibration and noise of the subway have an impact on the environment and the lives of residents, it has become the focus of people's attention to the construction of the subway. In order to effectively control the problem of subway vibration and noise, measures are often taken on the track structure, such as the use of fasteners, sleepers and ballast bed systems containing various polymer materials. At present, among the structural types of urban subway tracks, the steel spring vibration-isolation floating slab track structure has the best vibration reduction effect. In recent years, with the continuous emergence of new intelligent semi-active vibratio...
