This paper presents the results of laboratory and road tests of the special transport vehicle MANGUST aimed at assessing its ride comfort and vibration characteristics when traversing a single artificial road irregularity. Ride comfort is a key parameter determining the operational reliability, structural durability, and ergonomic quality of special-purpose vehicles, especially those operating under increased dynamic loads. The experimental study included registration of tri-axial accelerations on the vehicle frame and on the driver’s seat, followed by spectral analysis and evaluation of root-mean-square vibration levels at different vehicle speeds. The obtained results make it possible to identify the resonance range of the suspension system and to assess the influence of speed on the vehicle's vibrational response. The findings have been used to verify a mathematical model of the vehicle dynamics and provide the basis for further optimization of the suspension and tire systems.
