The invention relates to a gravity type stable triggering hammering modal test device and method, and the structure comprises a vertical threaded rod, the threaded rod is connected with a sensor, the sensor is connected with a hammer head, the sensor is in signal connection with a data collector through a signal line, and the threaded rod above the sensor is provided with a positioning plate. A butterfly clamp is arranged at one end of a cantilever plate at the top end of the main support to clamp the threaded rod, a hollow base is arranged at the bottom of the main support, the hammer head is located above the base and aligned with the center of the base, and it is guaranteed that the hammering position is located in the center of the base. A scale plate is arranged on one side of the threaded rod at the top of the base. The top of the base is provided with a hollow anti-continuous-hitting mechanism, the distance between the bottom of the positioning plate and the bottom of the hammer head is equal to the di
