The invention relates to a broadband response element applied to a rail train. The broadband response element comprises a metal substrate, a mass block and piezoelectric ceramics, the metal substrates are arranged in a sector ring structure, the piezoelectric ceramics are attached to the two faces of the metal substrates, the multiple metal substrates are arrayed in the circumferential direction to form a disc structure, the outer edge of the disc structure is clamped and fixed through a circular ring, and the multiple mass blocks are fixed to the two faces of the metal substrates at the inner edge of the disc structure respectively. According to the broadband response element applied to the rail train, the fan-shaped cantilever beams are arranged in the circumferential direction in an array mode, vibration energy in the vibration environment of the rail train can be collected through adjustment of element parameters on the fan-shaped cantilever beams, the working frequency width can be effectively widened, the energy collection and conversion efficiency can be improved, and energy collection and conversion are more stable.
