Mine roadway base plate and track dynamic characteristic analysis experimental device

The utility model relates to a mine roadway base plate and track dynamic characteristic analysis experimental device. The mine roadway base plate and track dynamic characteristic analysis experimental device comprises a rectangular rigid tank, wherein the rectangular rigid tank is internally arranged with multi-layer mine roadway base plate mineral mediums, steel tracks are laid on the base plate mineral mediums through sleepers, each layer of the base plate mineral mediums is respectively embedded with a plurality of piezoelectric pressure sensors internally, strain gauges are pasted on the steel tracks, the sleepers are provided with acceleration sensors, and output signals of each sensor and each strain gauge are all transmitted through a multi-channel amplifier and a DAQ card to a computer for processing. In a specific experiment, when a model of a mine vehicle runs, each sensor and each strain gauge arranged on a base plate, the sleepers and the steel tracks respectively acquire three type signals of pre
