The work aims to design a carbon fiber reinforced polymer (CFRP) storage and transport shelter based on the agile support model and validate its structural strength and reliability, so as to address the issues of poor support timeliness, wasted transportation capacity, and low transfer efficiency inherent in the traditional "single box packaging + bulk transport" mode for aviation ammunition. A new storage and supply support mode of "naked ammunition containerization" was proposed. A lightweight design was achieved by adopting a hybrid architecture combining T700 CFRP and 30CrMnSiA high-strength steel. Based on the Classical Laminate Theory (CLT) and the Tsai-Wu failure criterion, a refined finite element model of the anisotropic materials was established utilizing the ANSYS Composite PrepPost (ACP) module. Various extreme load cases, including vertical, longitudinal, and lateral impacts as well as hoisting conditions, were set to conduct static and modal analyses of the structure using the Finite Element Method (FEM). The simulation results indicated that under the extreme condition of 4.5g vertical overload, the maximum equivalent stress of the main shelter structure was 971.16 MPa, occurring at the column joints; the safety factors for the composite panels and critical load-bearing components were all greater than 1.5. However, the maximum stress of the internal bracket reached 1 022 MPa under extreme conditions, exceeding the yield strength of the material, which suggested the necessity for structural optimization through local thickening. The proposed storage and transport shelter design realizes high-density storage and the rapid support function of "integrated transport and loading". Its structural stiffness and strength meet the requirements of the environment. This study validates the application potential of composite materials in heavy-duty packaging equipment and provides a theoretical basis and technical support for the agile support of aviation ammunition.
