Abstract

This study proposed a dynamic forming mechanism development of the negative Poisson's ratio elastomer molds-plate to plate (P2P) forming process. To dynamically stretch molds and control the microstructural shape, the proposal is committed to using the NPR structure as a regulatory mechanism. The NPR structural and dynamic parallel NPR-molds to control microstructure mold-cores were simulated and analyzed. ANSYS and MATLAB were used to simulate and predict dynamic NPR embossing replication. The hot-embossing and UV-curing dynamic NPR P2P-forming systems are designed and developed for verification. The results illustrated that the dynamic forming mechanism of the negative Poisson's ratio elastomer molds proposed by this study can effectively control microstructure molds. This can effectively predict and calculate the geometrical characteristics of the microstructures after embossing. The multi-directional dynamic NPR microstructural replication process can accurately transfer microstructures and provide high transfer rate-replication characteristics.

摘要

本研究提出了一种负泊松比弹性体模具板对板（P2P）成型过程的动态成型机制。为了动态拉伸模具并控制微观结构形状，该方案致力于使用负泊松比结构作为调节机制。对负泊松比结构和动态平行的负泊松比模具以控制微观结构型芯进行了模拟和分析。使用ANSYS和MATLAB对动态负泊松比压花复制进行模拟和预测。设计并开发了热压花和紫外光固化动态负泊松比P2P成型系统进行验证。结果表明，本研究提出的负泊松比弹性体模具的动态成型机制能够有效控制微观结构模具。这可以有效预测和计算压花后微观结构的几何特征。多向动态负泊松比微观结构复制过程能够准确转移微观结构，并具有高转移率复制特性。
