摘要
较为详细地介绍了活化给料机的结构,利用集中质量法简化了力学模型,建立了转动的复杂动力学微分方程,通过求解方程,画出了x方向的幅频特性曲线和相对振幅曲线以及y方向上的幅频特性曲线。从振动特性方面来解释了活化给料机的运动特性。
Introduces the structure of the activating vibration feeder. The mechanical model is simplified by using lumped mass method,the complex dynamics differential equation is established also. By solving the equation, the amplitude-frequency characteristic curve and the relative amplitude curve of x direction and the amplitude-frequency characteristic curve of y direction are drawn. So explain the movement characteristic of the activation vibration feeder from the aspects of vibration characteristics.
