【摘要】：惯容器是一种双端子质量元件,在第二类机电比拟下,惯容器与电容完全相似。因此,惯容器的出现极大地推动了机械网络理论的发展。由于传统的惯容器以机械飞轮来实现其惯质,因此提高惯质将使其自身质量也随之增加。这限制了惯容器在对质量限制严格的工程中的应用。为提高惯容器的惯质质量比,本文设计了一种机电式惯容器,并对其性能进行了研究。本文的主要工作如下:(1)设计了机电式惯容器的电枢电路。经推导得到电枢电路应由电容、负阻抗变换器串联组成。通过负阻抗变换器抵消了绝大部分的电枢电阻、电枢电感,使得电枢电路呈容性,进而通过电容储能使电枢电路模拟了大质量的飞轮,增大了惯质质量比。(2)应用劳斯判据分析了机电式惯容器的稳定性。通过对其特征方程分析得到机电式惯容器稳定工作的条件为,电枢回路中必须存在一定的剩余电阻。(3)对机电式惯容器能够实现惯容器效应的工作范围进行了分析。以运算放大器不饱和、直流电机能产生电磁感应作为电枢电路的约束条件,得到了外力致使电枢电路失效的频率范围、幅值范围,并且该频率范围、幅值范围受到电枢电路中电容值的影响。(4)分析了电路参数对于机电式惯容器“力-速度”特性的影响。得到其只能在0Hz~10Hz的低频段近似成理想的惯容。并且随着电路中电容值的增大,其能够近似成理想惯容器的频率范围随之变窄。(5)讨论了机电式惯容器可实现的最大惯质。针对得到的许用受力范围,得到了电枢电路能够串入的最大电容值,进而得到了其理论上能够实现的最大惯质。(6)实验验证了机电式惯容器设计的可行性。研制了机电式惯容器的实验样机以及其测试平台。经测试得到,接入电枢电路后的机电式惯容器的惯质明显增加,且随电容的增大而增大。
[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.
