摘　　要：针对生物质颗粒机在加工成型燃料过程中关键部件平模和压辊磨损后导致使用寿命短、影响生产率等问题,对压辊进行了设计并采用Ansys软件对其进行有限元分析。仿真结果表明,设计的压辊在极限工况下应力为179.24MPa,应变0.038mm,平均疲劳安全系数达到2.4,符合材料特性要求。对样机进行试验表明,采用这种结构的生物质颗粒机的能耗低、产量大、产品品质高。In the machining process with burning,the wear of key components of biomass pellet machine is induced,which would lead to short life and affect productivity.The compression roller is designed and analyzed with finite element method.The simulation results show that under the extreme conditions,compression roller ’ s stress is 179.24MPa,strain is 0.038mm,its average fatigue safety factor is 2.4,and then it can meet the requirements of material properties.Also,this test shows that for using this device,the energy consumption is lower,the output is much greater and the quality of products is much excellent.
