TL;DR: In this article, a three dimensional viscoplastic constitutive model for finite strains in a co-rotational explicit scheme is developed and implemented using finite elements that capture the amplitude dependency, and it is shown that the model captures the amplitude dependence of the amplitude.

TL;DR: Dynamic transmission error (DTE) is widely accepted as the source of gear whine noise, therefore its reduction is essential for NVH optimization of drivelines.

TL;DR: For a rolling tyre, forces arise within the tyre-road contact patch, leading to the excitation of tyre vibrations and in turn to noise radiation, which is the main cause of highway noise and consequ...
