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°～14°。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 ele-ment analyses based on the mechanical models are done by ANSYS .The results show that the conical holes have a grea-ter 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 con-dition, reducing wearing and extending the service life of the ring die .
