機電類比法是一種把機械量通過一定的計算等效類比為電量的方法,其在對電子機械系統的分析中應用非常廣泛。它能夠把一個較復雜的機械系統類比為我們熟知的電路系統來進行分析,從而使問題的分析得到簡化。本文通過對振弦式傳感器的分析介紹了機電類比法,并對使用電路進行了相關的分析。 Summary:The electromechanical analogy is assort of analysis which is to analogize the mechanical system by using circuit system , it applied widely in the filed of analysis the electronic-mechanical system. The analysis can take a complex mechanical system analogous to a circuitry that we well-known, which can simplify the problems. In the paper, the electro-mechanical analogy method is briefly introduced by analysis the vibrating wire sensor,and have a correlation analysis about the circuit we used.關鍵詞: 機電類比法 振弦式傳感器 頻率 振蕩 反饋Keyword:electro-mechanical analogy method,vibrating wire sensor,frequency, Oscillation, feedback 0 引言振弦式傳感器是屬于頻率式傳感器的一種。所謂頻率式傳感器就是能直接將被測量轉換為振動頻率信號的傳感器,這類傳感器一般是通過測量振弦、振筒、振梁、振膜等彈性振體或石英晶體諧振器的固有諧振頻率來達到測量引起諧振頻率變化的被測非電量的目的,其也稱為諧振式傳感器[1]。在分析該類傳感器中,由于其涉及到頻率,就容易讓人聯想到在電子技術中接觸到的RLC振蕩電路。因此可以嘗試著用類比的方法使之對應起來分析,即機電類比法分析。

Functions, such as high-pass, band-pass, low-pass filtering, can be realized respectively and simultaneously, and can become a quadrature oscillator by modifying resistance ratio. Its pole angular frequency and quality factor can be tuned accurately and independently. The circuit presented contains four OPs, two capacitors, and eleven resistances, and inverting input of all OPs is virtual ground. Its general filtering, the independent control of pole frequency and quality factor and quadrature sinusoidal Oscillation were simulated by computer, and the result shows that the presented circuit is valid and effective.

These Simulink blocks contain transfer functions that model the pressure and flow transients for axisymmetric 2D viscous flow of a compressible fluid in a straight rigid circular cross section pipelines. Three models are available: (1) pressures at the ends (2) flow rates at the ends (3) pressure at one end and flow rate at the other Filtering is incorporated to reduce numerical Oscillation (Gibbs phenomenon).

This paper presents a new type of electromagnetic damper with rotating inertial mass that has been devel oped to control the vibrations of structures subjected to earthquakes. The electromagnetic inertial mass damper (EIMD) consists of a ball screw that converts axial Oscillation of the rod end into rotational motion of the internal flflywheel and an electric generator that is turned by the rotation of the inner rod. The EIMD is able to generate a large inertial force created by the rotating flflywheel and a variable damping force devel oped by the electric generator. Device performance tests of reduced-scale and full-scale EIMDs were under taken to verify the basic characteristics of the damper and the validity of the derived theoretical formulae. Shaking table tests of a three-story structure with EIMDs and earthquake response analyses of a building with EIMDs were conducted to demonstrate the seismic response control performance of the EIMD. The EIMD is able to reduce story drifts as well as accelerations and surpasses conventional types of dampers in reducing acceleration responses.
