| 摘要: |
| 为了降低瓦楞机振动噪声,有必要计算瓦楞辊振动模态和测试载荷频率。 利用 UG 创建了瓦楞辊的实体模型及其参数化表示,以及 UG 与 ANSYS 之间的专用接口;将 UG 建立的三维实体模型数据导入到 ANSYS中,利用 ANSYS 的模态分析功能,对瓦楞辊有预载荷不同辊长、无预载荷不同辊长和不同内径的情况进行了模态分析,得到了瓦楞辊 3 组前 10 阶模态的固有频率和固有振型数据,并将 3 组数据与实测载荷频率进行了分析比较,为瓦楞辊的减振降噪提供理论依据。 |

| Abstract: |
| To reduce the noise and vibration of corrugating machine, it is necessary to calculate the vibration modal and test the load frequency of corrugated roller. UG was used to construct the 3D model and parameteric presentation of corrugated roller as well as the special interface between UG and ANSYS. Data of the 3D model was introduced into ANSYS. The modal of corrugated rollers of different length in both load and unload condition was analyzed using the modal analysis function of ANSYS. The three groups of data consisting of 10 orders of natural frequency and mode of vibration was obtained and compared with the tested data. The purpose was to provide reference for antivibration and noise reduction of corrugated roller. |
