Optimization Design of Packaging Structure Based on Strength Analysis of ANSYS and Dynamic Testing Verification

The work aims to optimize the design of wooden packaging structure with a large consumption in a certain type of pump on the premise of ensuring the strength of mechanical structure, simulate the mechanical strength by CAE finite element method and carry out the vibration drop impact test to reduce the cost and improve the product value. Firstly, the use function of the product was analyzed and a new packaging scheme was designed. The original steel support structure was optimized to V-shaped wooden support structure and a mechanical model was established to analyze the bottom strength and calculate the stability. Then, SolidWorks was used to construct a 3D model and ANSYS Workbench was adopted for simulation and evaluation. Finally, a new packaging was produced and tested according to the packaging test standards. The new packaging structure replaced the iron baseboard support with V-shaped wood, saving the cost of iron packaging material 100%, and passed the impact, vibration and drop tests. The optimized design of the new packaging type could meet the protection requirements of the impact and vibration drop during the transportation process and satisfy the functional requirements of transportation stability. Guided by the value engineering, the optimized design of the new packaging structure reduces the cost while achieving the required function, which is an excellent application of value engineering in packaging optimization and provides design reference and solutions for packaging engineers in mechanical engineering field.
