摘　　要：在机械振动实验中,经常要建立机械实验系统,而建立机械实验系统本身有很多困难,比如说设备多,成本高,费时。这样,我们想到用其它模型来模拟机械模型。电路模型无疑是最适合的。本文用电路模型来模拟简单的隔振模型和动力吸振模型。分析及数值结果证明该电路模型实现了机械振动控制系统的本身的规律,可以实现预期的功能。这样,我们可用电学实验去实现机械振动控制实验。Mechanical experimental systems need establishing frequently, when mechanical vibration experiments are conducted. However, there are a lot of difficulties in establishing these systems, such as great amount of equipment, high cost and much time. Therefore, else model is considered to replace mechanical model, and circuit model is the most appropriate one without doubt. A circuit model is used to simulate simple isolation and dynamic absorber model in this paper. Analysis and numerical result shows that the laws of mechanical vibration control system are realized in this circuit model and the model can perform expected function. Thus, it can be concluded that mechanical vibration control experiments can be realized by electronic experiments.
