Numerical Simulation Analysis of Rotational Drop of Composite Material Packaging Container Based on LS-DYNA
The work aims to investigate the numerical simulation technology for rotational drop of composite packaging container by adopting ANSYS to display dynamic analysis of ultra large composite packaging containers.Based on the law of conservation of energy,the rotation and drop height parameter was converted into the angular velocity parameter of rotational drop as the rotational drop strength index.A rotational drop model for composite material packaging container based on numerical simulation analysis method was established by the LS-DYNA module of ANSYS,and multiple rotational drop conditions were simulated and analyzed.The results indicated that composite packaging containers could not withstand direct rotational drop impacts and required cushioning protection.At the impact site,a hard rubber cushion was applied to substantially reduce the stress,ensuring the stress below the allowable value of the material.Rotational drop represents one of the most susceptible impact modes for large packaging containers.By incorporating cushioning protection at the impact site for composite material containers,the safety can be ensured against both rotational edge drops and rotational angular drops of the packaging containers.
