The invention discloses a ship grillage moving impact load time domain rapid inversion method, and belongs to the technical field of large-scale structure load inversion, in the ship grillage moving impact load time domain rapid inversion method, a response base required by inversion is constructed based on an influence line matrix, rapid construction of any-order response bases is realized, high-order moving impact load rapid reconstruction can be realized, and the time domain of the ship grillage moving impact load can be rapidly reconstructed. The method overcomes the difficulty of structure calibration, can construct any order of load basis and structural response under the action of the load basis by influencing the line matrix data only by completing the calibration of the line matrix, thereby solving the problem that the traditional means does not have the feasibility of test calibration, and is simple and easy to implement, high in operability and reliability, and easy to popularize. The single-point moving impact load action time calendar can be obtained through accurate inversion based on known input, ship structure design and optimization are guided, and therefore the safety of a ship body structure in the life cycle of the ship body structure is guaranteed.
