Application of Finite Element Method to Study the Influence of Operation Conditions on Tire Performance

Abstract

The paper presents the results of a study applying numerical simulation to investigate the effects of load, pressure and speed on the performance of Bridgestone Ecopia EP422 tires. The 3D model of the research object was built using Siemens NX software and analyzed using Ansys Workbench. The main output parameters including deformation, stress and contact area were analyzed under various operating conditions. The results show that load directly affects the contact area; low pressure increases the contact area but reduces fuel efficiency; high speed reduces contact time and causes stress concentration at the sidewall. The simulation results are consistent with previous experimental studies, confirming the reliability of the model and its applicability in tire design and optimization. The topic opens up the potential for integrating advanced factors such as material nonlinearity, environmental impact and artificial intelligence in subsequent studies.
