The validation of computer models through experiments is essential and is the basis for the credibility of the results obtained from simulations. This paper presents a flexible, low-cost test bench design and a computer model of a quarter car system fitted with a regenerative energy suspension called BS-EHSA (Ball-Screw Energy Harvesting Shock Absorber). A good correlation between experimental results and simulations is obtained. Based on this validated model, a study of the influence of the different BS-EHSA design parameters is carried out in order to obtain optimal values for ride comfort, road handling, energy recovery and energy efficiency. An average power of 15.13 W is attained when the vehicle is driven at 70 Km/h on a road profile ISO 8608 standard class C roughness index.
