Finite Element Analysis And Optimization Of The Shell Structure Of Pulp Packaging

Packaging sructure industry has a rapid development with the achievement in numerical design and analysis.Design,manufacturing and other aspects of packaging products saw great advance with the increasingly progress in numerical technique.Finite element analysis and optimization are applied to the design of packaging shell structure in order to find the optimal structure under prescribed boundary conditions.The optimization of buffer plate,we analyzed a single round table unit through finite element analysis.The impact of its radius,height,thickness and other geometric parameters on load carrying capacity and buffering properties are discussed.The patten distance of unit cells is optimized with objective to get better structure performance.The finite element analysis of corrugated struture is implemented,and the effect of period and amplitude of the sine shape to buckling load was studied in this work.The performance of the different combination of cores was analyzed.The result provides theoretical guidance for the design corrugated board.A two-stage buffer egg tray structure is proposed for the long distance transporting and easy storage.The impact of different parameters of the structure on carrying capacity and buffering capacity was studied using finite element analysis.Computational results show that two-stage structure not only can improve the buffering capacity and increase the buffer time,but also increase the carrying capacity.Results show that the geometric parameters have an important influence on the performance of the pulp shell structure,which is a buffer mechanism related to the pulp shell structure;buffer by adding two columns,egg tray carrying capacity and buffering capacity are greatly improved and extended the buffer time.
