秸秆压块机环模工作受力分析与仿真研究

秸秆压块机是把秸秆等农作物剩余物压缩制成环保燃料或饲料的设备。环模是环模式秸秆压块机的关键工作部件，由于其直接参与物料挤压作用而易磨损。为研究环模在压块过程中磨损情况和对优化设计提供一定参考，现分析环模在压块过程中的受力情况，研究环模在工作过程中关键受力部位，应用ANSYS软件对该部位进行有限元静力分析，得出受力后应力分布及形变方式。研究结果表明，环模中的楔形部位为压块机环模在压块过程中的关键受力部位；通过仿真分析楔形部位受力情况，研究该部应力分布及形变方式，对于降低环模压块机环模的磨损及进行结构优化提供理论依据。

The Research on Force and Finite Element Analysis of Ring Die in Briquetting Process

Ring die is the key working part of the ring mold briquetting machine because of its direct participation in the material easy wear compression. To study the ring die wearing in the briquetting process and provide a reference for the optimal design, the force in ring die briquet- ting process was analyzed, critical parts of the force in the work process was studied. And the finite element analyses were clone by ANSYS. The results show that the wedge parts of the briquetting machine ring die is the key part of the force in the briquetting process. The stress distribution and deformation mode was studied to reduce ring die wearing and provide a theoretical basis for structural optimization.
