Abstract
This thesis discusses the application of Inerter to passive vehicle suspension control. We employ a new mechanical element – Inerter into vehicle suspension systems, combining it with traditional suspension elements. Inerter is a passive element like a spring or a damper. By the invention of Inerter, the mechanical network can be analogous to the electrical network perfectly. From the result of analysis, we find Inerter can improve the vehicle suspension performance potentially. Until now, several realizations of Inerters were constructed and tested. Due to mechanical construction, some nonlinearities of Inerter were noted. We discuss three kinds of nonlinearities – backlash, friction, and the elastic effect, and compare the theoretical and experimental results to verify the property of Inerters. Finally we discuss the influence of Inerter nonlinearities to vehicle suspension performance. It is shown that nonlinearities slightly decrease the performance benefit of Inerters.
