STRESS ANALYSIS TO IMPROVE THE STABILITY OF PACKAGING STRUCTURE COMPUTATIONAL SIMULATION—BASED ON MATERIAL STRUCTURE AND STRESS RESPONSE

In order to solve the problem of insufficient structural stability of plastic food packaging, this paper explores the relationship between the packaging structure and the maximum deformation of packaging under pressure from the perspective of mechanics, carries out force analysis on arch structure, and uses ANSYS finite element analysis system to explore the maximum deformation of packaging with different Gaussian curvature and different structures under the same pressure. This project designed a new type of arch packaging structure which can reduce the maximum deformation by 12.4%, and verified the feasibility of arch structure to improve the stability of packaging structure from two aspects of theory and numerical calculation. This experiment combines physical theory with practical application, designs a more stable food packaging structure, provides technical support and theoretical reference for the packaging express industry, and reduces environmental pollution caused by excessive food packaging.
