内燃机振动动力式主动吸振器的研究

振动主动控制技术具有减振效率高，有效减振频率范围度，反应敏捷等优点，在机械振动领域具有广泛的应用前景。在一台四缸柴油机上进行振动主动控制的研究，使用主动控制技术控制动力吸振式的频率，使其能足够发动机的主动振动频率，并保持最佳状态，从而有效地抑制发动机的振动。

A Study of Dynamic Type Active Vibration Absorbor for Intenal Combustion Engine Vibration

There are many advantages of the ective control technique of vibration such as high efficiency of oscillationreduction, wide frequency range of effective oscillation reduction and quick reaction etc, which possesses broad applicationprospect in mechanical vibration engineering field field. Ressearch work is carried out for the active control of vibration on a fourcylinder diesel engine by using the echve control technique to control dynamic absorbing type frequency to make it tracking themain vibration frequency of engine and keep it at an optimum state, so that the vibration of rngine is effectively suppressed.
