摘要
通过ANSYS有限元分析软件,对单螺杆挤出机的核心部件—螺杆部分进行模态分析计算其固有频率,并通过振动试验对仿真结果进行验证,结果表明通过有限元法对挤出机螺杆的模态仿真具有较高的可靠性。获得该螺杆前三阶固有频率后,结合螺杆实际工作状况对螺杆进行优化,采用增加螺杆的起始端固定段长度的方法有效降低螺杆一阶固有频率和振动幅度,避免共振的产生。为实际生产中,降低单螺杆挤出机振动、噪声,获得更加稳定的挤出产物提供新的解决方案,也为学者研究螺杆挤出机提供一种新的方法。
Based on ANSYS finite element analysis software, we analyze the modal of the core component of single screw extruder,the screw parts, and calculate its natural frequencies. Then we validate the simulation through the result of vibration tests. The results showed that the modal analysis of screw extruder is highly reliability with the finite element method. When the first three natural frequencies of screw are obtained, we combine with the actual working conditions to optimize the screw. The first natural frequency of screw and its vibration amplitude can be decreased through increase the screw＇s start fixed length to avoid resonance. It can reduce the vibration and noise of single screw extruder and provide new solutions to acquiring more stable extrusion products in the actual production. It also offers a new approach for scholars who study on the screw extruder.
