Construction of CFD-MBD Co-Simulation Technology for Improving the Performance of Cardboard Machine

Abstract

Demand for corrugated cardboard boxes has been increasing in recent years due to the expansion of the logistics market and restrictions on outings associated with global measures against infectious diseases. Our company is developing a carton making machine that can make corrugated cardboard faster than before. The flow field in the box making machine was reproduced by CFD, and the motion of the corrugated board was modeled by MBD (Multi Body Dynamics), and the Two-way coupled analysis model was constructed. The flight behavior of the corrugated fiberboard sheet can be predicted without trial manufacture using the construction model. In addition, it became possible to study the operation method and derive the optimum set value by parameter study.
