| Abstract: |
| The work aims to investigate the logistics material storage and transportation containerized equipment, validate the stability and reliability of the combination of materials that constitute the overall structure under extreme temperature and load constraints, and reduce production and manufacturing costs. The container was designed according to GJB 4361-2002 for 1C cabins, with Q235B profile for the container framework and Q355E corrugated cladding for the entire container structure. Through computational deduction and ANSYS simulations, and based on GJB 5727-2006, an extreme temperature environmental load storage test was conducted on the complete container. Throughcomprehensive study,the actual working performance of large-size containerized equipment under special conditions was examined. The results of deformation amountscomplied with the operating requirement under three constraints:normal temperature, –20 ℃, and –45 ℃. Experimental observations showed that the container worked stably and without structural failure under an environmental temperature of –45 ℃ and a local load of 5 tons. It is concluded that simulations and experiments support each other, demonstrating that dynamic stress dispersion occurs when Q235 series materials exceed their theoretical ductile-to-brittle transition temperature. The overall material combination and the closed-loop structure effectively compensates for deformations and locally enhances each other. Ultimately, a cost-effective logistics material storage and transportation containerized equipment that can adapt to heavy loads in a –45 ℃ environment is developed, providing strong support for future modular containerized equipment cost control, process design, whole container testing, and industrial research. |
