Analysis Of Dry Cargo Container Mechanical Properties And Optimal Design Based On ANSYS

Container transport has made a rapid development with the growing of national economy and freight. As a standardized cargo carrier container has been popularized around the world. Container will be the role of various external forces in process of cargo handling and transportation, while the container as the container the main floor and chassis components to withstand the force of which the majority of the role of external forces. While other components of the container, such as siding, roof, etc. are also attached to chassis. In the process of using the container, the deformation is affecting the performance of the major factors, therefore, in the container design, manufacturing process, the rigidity of chassis and chassis is that people are more concerned of.Building the container flooring and the chassis structure of the entity model by CAD software, using ANSYS finite element analysis software by the lateral load floor in the situation when the static analysis shows that the lower case of cross-height ratio, can significantly improve floor stiffness; at the same time, the flooring and chassis combinations under the car roll on static analysis, the results show that when the car in the middle of the flooring and chassis combinations the combination is the biggest, and appropriate reduction chassis beam spacing can improve the combination of stiffness; then, analyzed the modal of chassis, calculated its modal shapes and corresponding natural frequency, through the natural frequency and vibration mode of the chassis from the whole deformation problem, and understand the weaknesses of the chassis structure with the corresponding frequency, and provides the basis for the structural design of the chassis; Finally, made a parametric modeling of the chassis rails, using longitudinal section size as the design variables, and the total volume of chassis as the objective function, and using the optimized design module of ANSYS software, calculated the optimal size chassis longitudinal cross-section, approached the purpose of the reducing weight of chassis, saving raw materials.
