Abstract : according to the deep analysis of the typical punching process, the loading charts and the amplitude - frequency curves of straight side cnc turret press frame are obtained. in the end the dynamic response of a typical process is calculated using modal superposition method by fem software marc and the static and dynamic stress of some nodes is compared as well
文摘:根據板料沖裁時的工作負荷圖確定了數控回轉頭壓力機的動載荷譜，並通過傅立葉展開，獲得了壓力機的幅頻譜，最後通過marc軟體採用模態疊加法計算了典型沖裁時機身的動態響應，分析了其動態特性，並對特徵點的動靜態應力進行了比較。 -
