木文以 ６０ｔ卧式链片冲床为对象，使用多输入单输出模型的识别方法，对机床各主 要部件所辐射噪声在总声级中所占的比重进行了研究，结果表明：该冲床操作位置处的 噪声，主要由各部件的振动辐射所引起，其中以安装模具的底板为最高；其次为滑块。 这些研究结果对于重新设计或改进冲床结构具有重要意义。 Mu Wen to 60t horizontal chain punch as the object, the use of multiple input and single output model identification method, the main components of the machine noise radiation in the total level of the proportion of the total were studied, the results show that: the punch operating position At the noise, mainly caused by the vibration of the various components, of which the bottom plate to install the mold as the highest; followed by the slider. These findings are of great importance for redesigning or improving punch structures.
