Designing and Simulating a Mechatronic Inerter

Abstract:

Inerters are two-terminal mechanical devices, which can simulate masses. It is significant to increase the ratio of the inerters’ inertance to its mass for mechanical networks synthesis. In order to increase this ratio, this paper proposes a novel mechatronic inerter which adds its own inertance by utilizing the electromagnetic torque of DC motor. An external electrical circuit of the mechatronic inerter is designed to ensure the additional inertance. The model of the mechatronic inerter is built and simulated. The results show that, under the same moment of inertia, the inertance of the mechatronic inerter is far greater than that of the mechanical inerter.
