ANSYS的生物质成型机环模结构分析

The Structure Analysis of Biomass Ring Die Based on ANSYS

根据生物质压块环模成型机的成型过程和机理分析,研究了环模的受力状况,分析了物料变化对攫入角β选取的影响;建立了环模挤压力学模型,借助ANSYS有限元分析软件对环模孔进行了力学分析。研究结果表明,环模锥形孔对生物质原料的成型影响较大,且在锥点处y向应力最大,减小应力的最佳开孔角度为9°-1 4°。该研究能够为改善生物质压块成型机环模的受力状况、降低环模的磨损、延长环模的使用寿命提供理论依据。

According to the molding process and mechanism of straw biomass briquetting, this paper studies the force conditions of ring die and analyzes the influence of the swoop angle （β） in the different materials. Then the finite element analyses based on the mechanical models are done by ANSYS. The results show that the conical holes have a greater impact on molding of the biomass materials, and the maximum stress of Y axis locates at the cane point. The opening angle of 9°- 14° is helpful to reduce stress at the cane point. It has provided a theoretical basis for improving force condition, reducing wearing and extending the service life of the ring die.
