We were honored to have Thomas Feister from TriMech Solutions present at the 2026 SIMULIA Americas Users Conference in Novi, Michigan, May 13-14, 2026.

Abstract: 

TriMech and A3T LLC, the US Research and Development arm of Triangle Tyre Group, collaborated to simulate a next-generation non-pneumatic tire (NPT) using Dassault Systèmes’ 3DEXPERIENCE Platform. The tire incorporates a set of novel structural and material design features that have not previously been implemented in NPT architectures, presenting unique modeling and simulation challenges. Accurate representation of the complex geometry, heterogeneous material behavior, and load-bearing mechanisms required advanced FEA capabilities beyond conventional workflows.

3DEXPERIENCE SIMULIA Simulation functionality was critical in enabling robust meshing strategies for intricate internal features, precise definition of nonlinear material properties, and reliable modeling of mechanical connections between tire components. The integrated simulation environment supported efficient iteration and refinement of the design while maintaining solution stability and fidelity. The resulting analyses provided insight into structural response, load distribution, and deformation behavior under representative operating conditions. This work demonstrates the value of advanced FEA tools in supporting innovative non-pneumatic tire development and highlights the role of simulation in accelerating the evaluation of unconventional tire designs.
