基于瞬态动力学的数控转塔冲床床身动力学研究

摘要

In order to study the dynamics feasures of CNC turret punch press frame ,the authors conduct the transient dynamic analysis of the frame by using ANSYS Workbench finite element software , and the analysis results are compared with the experimental data ,to verify the correctness of the kinetic model of the frame .Based on accurate kinetic model ,the vibration control of the frame is performed ,and the measure of importing damping structure is taken .%为了研究数控转塔冲床床身的动力学特性，利用有限元分析软件ANSYS Workbench对床身进行瞬态动力学分析，并与实验数据进行分析对比，验证床身动力学模型。在得到准确动力学模型的基础上对床身进行振动控制研究，并引入阻尼结构进行床身振动吸收。
