Development of an HLFS agricultural tire model using FEA technique

This paper proposes a new high lug farm service (HLFS) agricultural tire size 220/70B16 tread design used for off-road agricultural operation. The HLFS tire is modeled using finite element analysis (FEA) technique in Visual Environment’s Pam-Crash software. The HLFS tire is designed using a combination of different materials including the Mooney–Rivlin material for tread. The Mooney–Rivlin material is an hyper-elastic material and it accurately resembles the mechanics and behavior of rubber used in tires. The FEA tire model is then validated against manufacturer’s provided data for several tire characteristics including radial, lateral, and tangential stiffness. This research will further continue to investigate the HLFS tire performance over clayey loam for different operating conditions.
