Abstract
A damper is responsible for the energy dissipation of a vehicle suspension, and, like any mechanical component, it is prone to wear. This paper addresses the analysis of a vehicle suspension frequency response along with the lifespan of dampers. The data considered in the proposed analysis was acquired using an accelerometer, which was installed in the car damper fixation. A set of tests have been conducted using two different dampers from the same model, but with different mileages: a brand-new one and an end-of-lifespan damper. Test results show that worn dampers present higher amplitudes at the natural frequency, as well as show a tendency of non-progressive behavior, which can compromise the vehicle stability.
