Hopkinson bar modular support test platform

The invention discloses a Hopkinson bar modular supporting test platform, belongs to the field of material dynamic mechanical property experimental equipment, and aims to solve the problems of the conventional Hopkinson bar supporting platform. The platform comprises p pairs of adjustable supports, m square positioning guide rails, (m+1) double-T-shaped groove row cutter plates and a box-shaped supporting platform, m+1 double-T-shaped groove row cutter plates are spliced and assembled on the box-shaped supporting platform in the length direction, lower positioning grooves are formed in the centers of the upper surfaces of the double-T-shaped groove row cutter plates in the length direction, and the m+1 communicated lower positioning grooves are positioned by continuously embedding m square positioning guide rails; two rows of T-shaped grooves are formed in the double-T-shaped groove row cutter plate in the length direction, and the two rows of T-shaped grooves are in central symmetry; and each pair of adjusta
