| Abstract | Retreaded tyres are commonly used on most highway trucks and buses for economic purposes in the logistics and transportation industry. In the retreading process the tread of worn pneumatic tyres with inspected tyre casing can be effectively remoulded. Nevertheless, an issue of the retreaded truck tyre energy efficiency remains a major challenging task in the industry nowadays. This research aims to obtain an effective simulated tool to determine the rolling resistance coefficient (RRC) of biased pneumatic retreaded truck tyres. In this work a finite element model was developed to predict the RRC for a tyre size of 10.00-20 with three tread patterns using ISO 28580-2009, which specifies methods for measuring the rolling resistance under controlled conditions. The simulated output variables include rolling resistance force, displacement and total strain energy. In addition, laboratory data were obtained through a series of experiments to verify the calculated RRC. The results show that a high degree of correlation between predicted and experimental RRC data can be found. As a result, an RRC prediction model of biased pneumatic retreaded truck tyres developed can effectively be used as a key parameter for fuel consumption improvement on retreaded tyre pattern design in the near future. |
