摘要
目的:分析澳洲坚果脱皮机中的关键部件脱皮辊的结构强度和振动特性,确定其各项工况参数。方法:将建立好的脱皮辊Solidworks模型导入Ansys中进行静力学分析和模态模拟。结果:当脱皮辊工作转速为861.4 r/min时,其最大变形为0.03208 mm,等效应力为11.872 MPa,正常工况下的最大等效应力远小于材料的屈服强度;其前6阶固有频率为111.44,111.46,345.34,345.71,503.23,681.05 Hz,远大于该脱皮辊的工作频率。结论:该脱皮辊的强度和刚度满足实际生产要求,且正常工况下不会发生共振。
Objective:To analyze the structural strength and vibration characteristics of the peeling roller,the key component of the macadamia nut peeling machine,and determine its working parameters.Methods:The established Solidworks model of the peeling roller was imported into Ansys for static analysis and modal simulation.Results:When the working speed of the peeling roll was 861.4 r/min,its maximum deformation was 0.03208 mm,and the equivalent stress was 11.872 MPa.The maximum equivalent stress under normal working conditions was far less than the yield strength of the material.The first six natural frequencies of the roller were 111.44,111.46,345.34,345.71,503.23,681.05 Hz,which were much higher than the working frequency of the peeling machine.Conclusion:The strength and stiffness of the peeling roller meet the actual production requirements,and there will be no resonance under normal working conditions.
