摘要
生物质成型机可以将松散的生物质原料(主要是农林废弃物)加工具有一定形状的成型燃料,对农林废弃物资源的再利用有着非常重要的意义。以HPB-V型液压式生物质成型机的成型套筒为研究对象,采用理论分析和Creo Simulate有限元分析相结合的方法,为成型套筒的制造材料选择提供思路和依据。成型套筒的基本参数:成型套筒出料直径为100mm,套筒锥长为240mm,锥角为8.4°,成型套筒材料为45钢和20CrMnTi钢。通过有限元分析,结果表明:两种材料在静力作用下都不会发生破坏,都适合加工制造成型套筒,但在工作过程中45钢成型套筒会发生疲劳损坏,20CrMnTi钢成型套筒不会发生疲劳损坏,因此,20CrMnTi钢更适合加工制造成型套筒。
Biomass molding machine can make the loose biomass raw materials,(mostly forestry and agricultural residues)into the shaped briquettes fuel.It is significant for the recycling of forestry and agricultural residues.The HPB-V hydraulic type of biomass molding machine's forming sleeve was the object of the study.Based on the theoretical analysis and Creo Simulate finite element analysis,it would find the basis of the materials of forming sleeve.The essential parameter of the forming sleeve were designed:the diameter of the forming sleeve was 100 mm,the length of the sleeve was 240 mm,the cone angle was 8.4°,and the forming sleeve materials were 45 steel and 20 CrMnTi steel.Based on the finite element analysis,the results show that the two materials did not break under static force,and were suitable for processing and forming the forming sleeve.However,during the working process,the 45 steel forming sleeve would be suffered fatigue damage,and the 20 CrMnTi steel forming sleeve would not be suffered from fatigue damage.Therefore,20 CrMnTi steel was more suitable for processing and forming the forming sleeve.
