The railway wheel flat scar signal acquisition device developed by the company includes: the steel rail as the force-bearing element of the load cell, and the adhesive or weldable strain gauges are fixed on the neutral axis of the steel rail, and the strain gauges are symmetrically installed on the two sides of the rail waist. The measurement area is formed on the side, and the strain gauges of each measurement area are connected to form a Wheatstone bridge. The railway wheel flat scar signal acquisition device proposed by the utility model has a simple circuit, reduces the cost of the equipment, and can quantitatively detect the size of the flat scar.
