利用试验模态技术对锡林墙板进行模态分析,通过建立合理的网格模型,采用脉冲激励的方式获得传递函数,进而得到其低阶模态各种典型振型,为大型圆板类铸件振动时效工艺参数的制订提供了参考。
The experimental modal analysis is used to analyze the modal properties of the cylinder plates. By establishing a reasonable grid model and using the pulse excitation method, the transfer function is obtained, and all the typical modes of the low-order modes are obtained. Vibration aging casting process parameters provide a reference.
