The utility model relates to the technical field of drivers for large blast wave simulators, and discloses a dual-driver for the large blast wave simulators. The dual-driver comprises a multi-tube blast driver (1), an atmospheric air chamber multi-diaphragm driver (2) and a multi-point type non-electric initiation system (3), wherein a plurality of single drivers (17) of the multi-tube blast driver (1) are fixed in a counterfort type reaction wall (15), and front ends of the single drivers (17) are located in a high-pressure section (4); a diaphragm and high-pressure packer structure (32) of the atmospheric air chamber multi-diaphragm driver (2) is located at an outlet end of the high-pressure section (4); a plurality of diaphragms (38) are mounted on one side, which is close to a high-pressure air chamber, of a main body frame of the diaphragm and high-pressure packer structure (32). The dual-driver has the advantage that blast shock wave environment simulation is realized with various combined driving methods and has the characteristics of high controllability, good repeatability, high efficiency and safety.
