项目摘要

In this project we develop an electric generator type damper with DC motor (named as a mechano-electric-damper) and its mechanical model based on the experimental dynamic behavior of developed damper. The device developed here is an adjustable damper equipped with a electric current control unit.The recently assembled HSCES (Hybrid Structural Control Experimentation System) is used to investigate structural control efficiency not only the developed but oil variable dampers. The system is equipped with high speed digital signal processing (DSP) units that allow wide flexibility for the investigation of different types of structural models and control devices. The HSCES can be used to test different types of structures responses to non-stationary excitations and to study the efficiency of real-size control devices in reducing structural response. The basic characteristic of the system is its ability to simulate the features of a particular structure and control device by DSP units. In th … More is system the control signal output unit, controller unit and structural model unit are interconnected. The system consists of five units : a seismic wave generating unit, response analysis unit, control unit, digital filter unit, controller device unit.The major advantage of the HSCES is that it not only tests of real models but analyzes numerically simulated models simultaneously. Because we can compute the response of the structure and the control device in real time it is possible to synchronize the input and output signal. Even if we do not test an entire structural model, we can perform vibration control experiments. That is, we can simulate the response motion of the model by using DSP and reproduce various experimental conditions. This system can properly reproduce the time lag of the signal transmission by using real-time numerical computation. We can also very easily change the particular structure to be tested by substituting for its simulated model, a new object model/code for the DSP, so that it is possible to consider large structures, high excitation levels or both.

在这个项目中，我们开发了一种带有直流电机的发电机式阻尼器（称为机电阻尼器）及其基于所开发阻尼器的实验动态行为的机械模型。这里开发的装置是一种配备有电流的可调阻尼器。最近组装的 HSCES（混合结构控制实验系统）不仅用于研究开发的结构控制效率，还用于研究油可变阻尼器的结构控制效率。该系统配备了高速数字信号处理 (DSP) 单元，可实现广泛的灵活性。 HSCES可用于测试不同类型结构对非平稳激励的响应，并研究实际尺寸控制装置降低结构响应的基本特性。系统的特点是能够通过DSP单元模拟特定结构和控制装置的功能。该系统由五个单元组成：控制信号输出单元、控制器单元和结构模型单元。生成单元、响应分析单元、控制HSCES的主要优点是它不仅可以测试真实模型，还可以同时测试数值模拟模型，因为我们可以实时计算结构和控制装置的响应。即使我们不测试整个结构模型，也可以进行振动控制实验，即使用DSP来模拟模型的响应运动并重现各种实验条件。正确再现信号传输的时滞通过使用实时数值计算，我们还可以通过替换其模拟模型（DSP 的新对象模型/代码）来轻松更改要测试的特定结构，以便可以考虑大型结构、高激励水平。或两者皆有。更少
