非线性自振荡振动系统的研究

Study on non-liner self - shaking & vibration system

利用非线性控制系统的自振荡特性、建立无输入的具有稳定频率和振幅的振动系统。而且.通过改变系统中的非线性环节的参数来调整自振荡的频率和振幅。这种系统无单独信号发生装置.故结构简单,可靠性好。用液压系统来实现.可以做到噪声小、故障低、易于控制、设备寿命长。是工程和工业生产的良好的振动设备。

Utilizing the self - vibration character nonlinear control system. We can establist the vibration system with stable frequency and amplitued. But, through change factor of nonlinear loop in the system, it can adjustes frequency and amplitude of self-vibration system. Without signal producer, the struction is simple and the reliability is high. Using on hydraulic system, the system is low -noise; high -reliability; easy-control; long -using time. It is good equipment for engineering and industrial production.
