摘要
根据板料折弯时的工作情况分析 ,确定了数控液压折弯机的动载荷谱 ,并通过傅立叶展开 ,获得折弯机的幅频谱。最后通过MARC软件采用模态叠加法计算了典型折弯时床身的动态响应 ,分析了其动态特性。
According to the analysis of the pressing process, the loading charts of CNC hydraulic press-brake are obtained. And the amplitude-frequency curve of the press-brake are obtained by Fourier transform.The dynamic response of a typical pressing process for press-brake frame is calculated by using the modal superposition method of MARC software.
