The paper aims to study the dynamic characteristics of a new structure missile package. The finite element analysis method was used to analyze the modal and random vibration. The natural frequency and vibration mode of the missile package and the dynamic response results of the structure under random load were obtained. The first 6 natural frequencies of the missile packing cases were distributed within the range of 13~44 Hz. Under the action of random loads, the maximum stresses in the three directions of the missile packing cases were 97.6 MPa, 149.3 MPa, and 151.1 MPa. According to the dynamic response of the mis-sile box, the dangerous parts of the box under random vibration environment were determined. The overall structure meets the design requirements under the random road loading. It provides a basis for design and verification of the missile packaging system.
