摘　　要：采用齿轮辊压成形薄板微流道结构,利用啮合原理实现微流道逐步弯曲成形,可实现高深宽比微流道成形。但成形中齿轮多种特征参数显著影响微流道成形减薄、失效,目前研究较少、难以指导工艺设计,限制了工艺的应用。因此本文结合微流道辊压成形实验与仿真,揭示了不同齿轮齿数、模数以及板厚、成形深度对减薄率的影响及原因,并提出了微流道辊压成形的成形深度-减薄率加权指标的响应面工艺参数优化方法。Metal sheet microforming with a gear as the roller provides a way to use the clench of the gear teeth to form the micro channels with high aspect ratio gradually.But some parameters of the gear have significant impact on the thickness reduction and structure failure.The lack of research on this topic restricts the application of the method.This paper shows the influence of the number of teeth,modules of the gears,thickness of the sheet and the forming depth on the results of the experiments and simulations.Finally,a parameter optimization method is presented using the response surface with weighted forming depth and thickness reduction.
