The effects of tyre material and structure properties on relaxation length using finite element method

Prediction of tread block forces for a free-rolling tyre in contact with a rough road

Tire safety is a pretty important performance for the vehicle. To overcome some disadvantages of the conventional pneumatic tire, a new non-pneumatic mechanical elastic wheel (ME-Wheel) is developed, and the camber performance of ME-Wheel is studied with numerical and experimental methods. A nonlinear three-dimensional finite element model of the ME-Wheel, which includes material nonlinearities, large deformation and the anisotropy of rubber–cord composites, is established. The rubber components of the ME-Wheel are analyzed by Moony–Rivlin model. With a vertical test rig, static loading tests are performed to validate the accuracy and reliability of the finite element model. Experiments and simulations under the static and rolling conditions are conducted to study the influence of different camber angles on the vertical stiffness, wheel deformation, contact pressure distribution and wheel force at the interface. The simulation results and the test results are compared and discussed in detail. The results show that the proposed method is useful for the investigation of mechanical characteristics of ME-Wheel and the later optimal design.

Determination of rolling tyre modal parameters using Finite Element techniques and Operational Modal Analysis

Dynamic behavior of a pneumatic tire is simulated by use of an explicit finite element (FE) code. Different parts of the tire and their corresponding material properties are taken into account in the FE model because they play a significant role in tire dynamics. The work presented in this study discusses simulation of cornering behavior, braking behavior, and combined cornering‐cum‐braking behavior. The effects of camber angle and grooved tread on tire cornering behavior are discussed. ABAQUS/Explicit, a general non‐linear FE code, was used for these simulations. To predict the Magic Formula characteristics over a complete range, various simulations are performed at different normal loads and operating conditions. Predicted Magic Formula curves from the simulation results for various dynamic conditions closely follow the experimental data curves. Even though these simulations demand huge computational resources, the predicted Magic Formula curves can be directly used as input in the complete stu...
