It is well known that the mechanical and electrical networks are analog to each other, namely the “force-voltage” and “force-current” analogies. However, there is a long-lasting gap in these analogies due to the mass element in mechanical systems. The invention of Inerter bridges this gap, and makes the mechanical and electrical networks truly analog. Meanwhile, Inerter is shown to be a very useful mechanical element in that it can significantly improve the system performance, and simulate a heavy mass inside systems. With the real analogy between mechanical and electrical networks, this project first considers several mechanical systems and their equivalent electrical networks. We will discuss their equivalence by the systems’ impedance and admittance, and verify the results by experiments. We will also apply the Inerter to vehicle and train suspension system designs, and the anti-vibration design of buildings to show the benefits of Inerter over traditional mechanical elements.慣質機械網路系統電子網路系統阻抗容度InerterMechanical NetworkElectrical NetworkImpedanceAdmittance慣質在等效機械/電子網路系統之應用.
