Structural design, static simulation and experiment of an aviation support carrier platform
To address the limitations of traditional aviation support transportation equipment, including single-function configuration, insufficient mobility, and limited modular adaptability, this study focuses on the structural design and performance verification of an aviation support carrier platform. Based on the systematic function analysis principle of TRIZ theory and the general concept of modular product design, an “application requirements-design functions” mapping system is established. Three core design requirements are identified, namely functional adaptability, load-bearing reliability, and modular expandability. According to the mapping results, the main body of the aviation support carrier platform is designed as a “longitudinal beams-transverse beams” rigidly connected frame with Q235 square steel, equipped with a “base seat + adjustable bolt” container locking system for rapid fixation and adaptation of various support carriers. Static mechanical simulation under a rated load of 5 tons is carried out using CATIA. The results show that the maximum equivalent stress of the platform is 39.8 MPa, and the maximum deformation is 0.131 mm, both of which are within the allowable engineering range. Furthermore, a static load-bearing verification experiment is carried out on the physical prototype; under 1.2 times overload (6 tons), the measured maximum deformation is 0.156 mm, which is consistent with the simulation results and within the engineering allowable range. No permanent deformation, weld cracking, or structural loosening is observed, verifying that the strength and stiffness of the aviation support carrier platform meet the design requirements. The proposed modular and adaptive platform realizes the design objective of “one platform with multiple functions” and supports low-cost functional expansion. The research provides a technical reference for the generalization, modularization, and integrated development of aviation ground support equipment.
