Abstract
<div class="section abstract"><div class="htmlview paragraph">Potholes are a major cause of discomfort for riders and vehicle damage. The passive suspension systems which are used in the passenger vehicles are primarily reaction based. These can’t adapt to the changing road conditions which means the best ride quality and handling characteristics cannot be ensured for different driving situations. Passive suspension system also needs more maintenance due to its inability to reduce the impact of the road irregularities. In recent years, semi-active suspension systems have been developed to improve ride comfort and vehicle safety. This paper covers the integration of a semi-active suspension system with a road preview mechanism with a TATA car model to investigate its impact on ride comfort, handling characteristics and component loads in digital domain.</div><div class="htmlview paragraph">A quarter car vehicle model is used to compare different active damping control strategies. The best strategy is selected and integrated in a full vehicle MBS model to gain deeper insight on ride and loadpaths.</div><div class="htmlview paragraph">The simulation results show that the proposed system reduces the vertical acceleration and displacement of the vehicle during pothole impacts. The system also improved the vehicle's pitch, roll and other critical characteristics. Loads on different suspension components also reduced.</div><div class="htmlview paragraph">Adoption of semi-active suspension systems in a TML passenger cars would lead to a transformation in the performance of ride comfort, handling dynamics and enhanced component life. The proposed system provides a practical and cost-effective solution to address the issue of potholes and has a positive impact on vehicle dynamics during pothole impacts. Overall, it will provide a more dynamic, comfortable and safer driving experience, making it a choice for a high performance car.</div></div>
