基于有限元的柔性压辊接触变形特性研究
Contact Deformation Characteristics of Flexible Compaction Roller Based on Finite Element Method
摘要
Abstract
In the process of Automated Fiber Placement(AFP),the placement quality directly impacts the performance of the formed components.The placement quality is closely related to the contact stress during the rolling process of the compaction roller.Therefore,it is necessary to study the contact deformation characteristics of the compaction roller.The research group took the flexible silicone rubber compaction roller of the fiber placement head as the research object,and proposed a method to explore contact deformation characteristics of compaction roller based on ABAQUS finite element simulation.Hyperelastic constitutive model parameters of silicone rubber was obtained by experiment.A contact model between the flexible roller and the placement mold was established to analyze the influence of roller hardness and pressure on contact stress and roller deformation.Relationships among various parameters were fitted out.The correctness of the finite element model is validated by compaction roller placement experiments.The research of the research group provides a reference for the design and optimization of compaction rollers.关键词
