This paper investigates the influence of ball-screw inerter nonlinearities on the vibration isolation performance of the vehicle suspension system. That is achieved by building a nonlinear mechanics model of the ball-screw inerter with friction in ball-screw assembly and elastic effect of screw. The parameters of the nonlinear mechanics model are identified using recursive least squares algorithm based on test data. Then, the nonlinear ball-screw inerter is applied to vehicle suspension analysis of the half-car model with three passive suspension layouts. The performance of the vehicle suspension system with the nonlinear ball-screw inerter is compared with that with the linear inerter. It is demonstrated from the results that the vibration isolation performance of the vehicle suspension system is slightly influenced by considering the ball-screw inerter nonlinearities in general. The influence of the ball-screw inerter nonlinearities on every performance indicator for different suspension layouts is discussed finally.
