To study the drop safety problem of a certain type of ship board solid rocket motor, the numerical simulation and analysis for the multi angle drop process at drop height of 37.5 m of solid motor were carried out by using ANSYS/LS-DYNA finite element analysis software. The verified test for drop test of real motor was performed. The results show that the dangerous angle at the same drop height is 78°, the temperature rise of charge in the motor calculated by ignition and growth model is less than 5 K, and the ignition reaction does not happen. The contact position of motor tail with collision surface is relatively dangerous. The stress and strain values of shell and internal charge are large, which may generate fracture failure. Through the drop test of solid rocket motor, it is found that the tail of motor has a fracture damage, but the ignition or explosion reaction do not occur. Data information collected from the test is consistent with the results of finite element analysis. The rationality of the calculation method is verified.
