The invention discloses a bridge with a damper of rotating-reciprocating friction. According to the key points of design, a gear is arranged in a first section central rotating shaft, the first section central rotating shaft and a second section central rotating shaft are in the same straight line, a third section central rotating shaft is arranged between the first section central rotating shaftand the second section central rotating shaft, a first middle reciprocating friction unit is arranged on the third section central rotating shaft, a first middle driving plate is provided with a strip-shaped groove, and first middle friction plates are arranged at the two ends of the first middle driving plate correspondingly; and the third section central rotating shaft is inserted into the strip-shaped groove of the first middle driving plate, vertical clamping grooves are formed in the sides, opposite to each other, of lateral plates, clamping strips corresponding to the clamping grooves are arranged on both sides of the first middle driving plate correspondingly, and the first middle friction plates are in contact with the lateral plates. According to the bridge with the damper of rotating-reciprocating friction, the problem of shock absorption and energy consumption of the bridge is solved.
