基于APDL的瓦楞纸板压痕折叠过程的仿真

Simulation on the Creasing and Folding Process of Corrugated Board Based on APDL

基于APDL(ANSYS Parametric Design Language)语言建立了瓦楞纸板仿真模型,运用接触分析及MPC(Mul-tipoint Constraint)技术,在考虑瓦楞纸板材料非线性及几何非线性的基础上,对瓦楞纸板的压痕及折叠过程进行了模拟仿真,得到了瓦楞纸板的变形图、最大应力及应力分布情况,为完善工艺流程提供了理论依据。

The APDL （ANSYS Parametric Design Language） was used in this paper to simulate the creasing and folding process of corrugated board. First a corrugated board model was built up. Then contact analysis and MPC （Multipoint Constraint） technology was used in the course of simulation with considering geometric nonlinear and nonlinear material of corrugated board. At last the results including deformation map of corrugated board, maximum stress and stress distribution map were given, which provide a theoretical basis for improving the process.
