Abstract
Based on force-current analogy and velocity-voltage analogy in the theory of electromechanical analogy, the inerter is a device that corresponded to the capacitor completely where conquers the nature restriction of mass, what’s more, it is significant to improve the ratio of the inerter’s inertance to its mass for mechanical networks synthesis. And according to the principle of active-control-based mechatronic inerter, we present two implementation schemes. One was based on linear motor, and the other was based on the ball screw and rotary motor. We introduced the implementation methods and established theoretical model of the two schemes, then compared the ratio of the inerter’s inertance to its mass for the two schemes. Finally, we consider the scheme is better which was based on the ball screw and rotary motor.
Highlights
In 2002, the concept of inerter was proposed by Malcolm C
The concept of inerter was put forward, which solved the problem that the mass only as single terminal mass components relative to the inertial system, and the mechanical network and circuit network can be strictly corresponding to the force–current analogy [4]
F applied to the two terminals of the linear motor based ACBMI, the output torque of the rotary motor with mass of M2 is TR, the force analysis of the inerter is as shown in figure 3
Summary
In 2002, the concept of inerter was proposed by Malcolm C. The concept of inerter was put forward, which solved the problem that the mass only as single terminal mass components relative to the inertial system, and the mechanical network and circuit network can be strictly corresponding to the force–current analogy [4]. It has important theory and application value for applying circuit theory to mechanical network synthesis. We can choose a better implementation scheme by comparing RMI
