The invention discloses a bending elastic impact vibration detection and analysis method and apparatus for a horizontal steel wire rope. The apparatus comprises fixed standing columns, steel wire ropeconnecting members, a pre-tightening system, a bending and triggering system and a measuring system. The left and right fixed standing columns are arranged and are used for fixing two ends of a steelwire rope; the space between the standing columns is kept to be larger than the length of the steel wire rope by about 1.5cm to leave the mounting space for a tension sensor and the like. The standing columns are fixed to the ground firmly, so that the pretightening force of the steel wire rope is met and the standing columns are protected from deforming and shaking during the ejection process. The steel wire rope connecting members are two wedge-shaped blocks specially for the steel wire rope and are connected with the two ends of the steel wire rope; with the wedge-shaped blocks, the steelwire rope is strained tightly and the rope ends are prevented from being loosened during the ejection process. According to the invention, with the disclosed method and device, the steel wire rope releases the ejection condition instantaneously under different pre-tightening forces at different bending angles; and the volatility state and the transfer mode of the ejection tension and vibration ofthe steel wire rope on the rope string are detected and analyzed.
