【摘要】：慣容器是一種雙端子質(zhì)量元件,在第二類機(jī)電比擬下,慣容器與電容完全相似。因此,慣容器的出現(xiàn)極大地推動(dòng)了機(jī)械網(wǎng)絡(luò)理論的發(fā)展。由于傳統(tǒng)的慣容器以機(jī)械飛輪來實(shí)現(xiàn)其慣質(zhì),因此提高慣質(zhì)將使其自身質(zhì)量也隨之增加。這限制了慣容器在對(duì)質(zhì)量限制嚴(yán)格的工程中的應(yīng)用。為提高慣容器的慣質(zhì)質(zhì)量比,本文設(shè)計(jì)了一種機(jī)電式慣容器,并對(duì)其性能進(jìn)行了研究。本文的主要工作如下:(1)設(shè)計(jì)了機(jī)電式慣容器的電樞電路。經(jīng)推導(dǎo)得到電樞電路應(yīng)由電容、負(fù)阻抗變換器串聯(lián)組成。通過負(fù)阻抗變換器抵消了絕大部分的電樞電阻、電樞電感,使得電樞電路呈容性,進(jìn)而通過電容儲(chǔ)能使電樞電路模擬了大質(zhì)量的飛輪,增大了慣質(zhì)質(zhì)量比。(2)應(yīng)用勞斯判據(jù)分析了機(jī)電式慣容器的穩(wěn)定性。通過對(duì)其特征方程分析得到機(jī)電式慣容器穩(wěn)定工作的條件為,電樞回路中必須存在一定的剩余電阻。(3)對(duì)機(jī)電式慣容器能夠?qū)崿F(xiàn)慣容器效應(yīng)的工作范圍進(jìn)行了分析。以運(yùn)算放大器不飽和、直流電機(jī)能產(chǎn)生電磁感應(yīng)作為電樞電路的約束條件,得到了外力致使電樞電路失效的頻率范圍、幅值范圍,并且該頻率范圍、幅值范圍受到電樞電路中電容值的影響。(4)分析了電路參數(shù)對(duì)于機(jī)電式慣容器“力-速度”特性的影響。得到其只能在0Hz~10Hz的低頻段近似成理想的慣容。并且隨著電路中電容值的增大,其能夠近似成理想慣容器的頻率范圍隨之變窄。(5)討論了機(jī)電式慣容器可實(shí)現(xiàn)的最大慣質(zhì)。針對(duì)得到的許用受力范圍,得到了電樞電路能夠串入的最大電容值,進(jìn)而得到了其理論上能夠?qū)崿F(xiàn)的最大慣質(zhì)。(6)實(shí)驗(yàn)驗(yàn)證了機(jī)電式慣容器設(shè)計(jì)的可行性。研制了機(jī)電式慣容器的實(shí)驗(yàn)樣機(jī)以及其測(cè)試平臺(tái)。經(jīng)測(cè)試得到,接入電樞電路后的機(jī)電式慣容器的慣質(zhì)明顯增加,且隨電容的增大而增大。
[Abstract]:The inertial container is a kind of double terminal mass element. Compared with the second kind of electromechanical, the inertial container is completely similar to the capacitance. Therefore, the emergence of inertial containers has greatly promoted the development of mechanical network theory. Because the traditional inertial container realizes its inertial quality by the mechanical flywheel, the quality of the inertial vessel will increase with the increase of the inertial quality. This limits the application of inertial containers in projects with strict quality restrictions. In order to improve the inertial mass ratio, an electromechanical inertial container is designed and its performance is studied. The main work of this paper is as follows: (1) the armature circuit of the electromechanical inertial vessel is designed. It is deduced that the armature circuit should consist of capacitor and negative impedance converter in series. By negative-impedance converter, most armature resistors and armature inductors are eliminated, which makes armature circuit capacitive, and the armature circuit simulates high quality flywheel through capacitive energy storage. The mass ratio of inertial mass is increased. (2) the stability of electromechanical inertial vessels is analyzed by using the Rouse criterion. Through the analysis of the characteristic equation, the conditions for the stable operation of the electromechanical inertial vessel are obtained: there must be a certain residual resistance in the armature circuit. (3) the working range of the electromechanical inertial vessel can realize the effect of the inertial container is analyzed. With the op-amp unsaturated, DC motor can produce electromagnetic induction as the constraint condition of armature circuit. The frequency range, amplitude range and frequency range of armature circuit failure caused by external force are obtained. The amplitude range is affected by the capacitance in armature circuit. (4) the influence of circuit parameters on the "force-velocity" characteristic of electromechanical inertial vessel is analyzed. The ideal inertial capacity can only be obtained in the low frequency range of 0 Hz ~ 10 Hz. With the increase of capacitance in the circuit, the frequency range of the ideal inertial container becomes narrower. (5) the maximum inertial mass of the electromechanical inertial container is discussed. According to the allowable force range, the maximum capacitance value of armature circuit is obtained, and the maximum inertial mass can be realized theoretically. (6) the feasibility of the design of electromechanical inertial vessel is verified by experiments. The experimental prototype of electromechanical inertial container and its test platform are developed. The test results show that the inertial quality of the electromechanical inertial vessel increases obviously and increases with the increase of capacitance.
