Gearbox shell constraint modal test method, equipment, storage medium and device

The invention discloses a gearbox shell constraint modal test method, equipment, a storage medium and a device, and the method comprises the steps: carrying out the modal analysis of a gearbox shell through a preset modal test model, determining the constraint modal shape of the shell, arranging a sensor according to a sensor arrangement reference point, carrying out the grid division of the constraint modal shape of the shell, and carrying out the grid division of the constraint modal shape of the shell; and taking the center of each grid as a hammering point, performing a simulated hammering test on the gearbox shell, and acquiring simulated hammering test data by each sensor. Since modal analysis is carried out on the gearbox shell through the preset modal test model to determine the shell constraint modal shape, and the simulated hammering test is carried out according to the hammering point, compared with the prior art that the modal test is manually intervened, the accuracy of a digital model is not hig
