Modelling and validation of shock absorption with tunable performance through liquid intrusion-extrusion cycles.

ABSTRACT: In response to the global push for net-zero emissions, the automotive industry faces challenges from the environmental impact of traditional oil-based shock absorbers, as vehicle production in Europe consumes around 9000-9500 tons of hydraulic oil annually. Our research introduces an innovative shock-absorber that employs a Heterogeneous Lyophobic System (HLS) to replace hydraulic oil with a nonwetting liquid (NWL) and hydrophobic nanoporous materials (PMs). This system not only eliminates oil use but also enables the tuneability of the vehicle shock-absorber's performance. By focusing on the dynamic intrusion/extrusion process, we developed a CFD-coupled model demonstrating how the adjustment of damping characteristics can be achieved, catering to a broad spectrum of vehicular requirement
