Vehicle performances in Crash related events like Small offset rigid barrier tests are crucially dependent on Tire-Wheel modelling. The objective of this study is to develop a detailed tire-wheel model subjected to loading, performance and failure criteria. The modelling technique should be robust, replicable and stable across a wide spectrum of simulations cutting down on unnecessary delays.
This project evaluates the options offered in LS-dyna (damping, loads, sensors, materials etc.) and current states of models being widely used. There is a focus on offering additional tools in the model for analyst to control the failure and model behavior. This tire-wheel model is subjected to scrutiny at multiple levels namely standalone, sub-system and full vehicle. The results achieved on this new modelling technique shows confidence in this. This model checks all the right boxes in terms of robustness, efficiency and development. The correlation is better on subsystem level tests. Tire-wheel modelling is critical to crash and also difficult due to unavailability of important information at times. With this model, analyst gets an easy option to play around model. It is easier to debug and locate the issues.
