For automotive coatings that are a multi-layered polymer composite structure, the impact-induced failure brings harm to the appearance, corrosion resistance, and safety of a vehicle, and thus this topic has drawn wide attention. The involvement of large deformation poses a significant challenge to coating delamination modeling. Considering this, we...
In recent decades, extensive effort has been devoted to simulating the tractive performance of an off-road tire on granular terrain using the combined discrete element and finite element (DE-FE) method. Previous works normally idealized irregular gravel materials using spherical DEs, requiring an artificial rolling resistance moment to deal with th...
The traveling analysis of an off-road tire on granular terrain is a typical application of contact interaction problems between structures and granular particles. In previous studies, extensive efforts normally idealized irregular gravel materials using spherical discrete elements (DEs), and the influence of irregular shapes was ignored. In our rec...
The real sand is usually idealized by using upscaled particles, due to the large number of particles of tire-sand interaction. This study aims to determine a unique and complete set of DEM-FEM model parameters to improve numerical accuracy of tire-sand interaction after particles idealization. To achieve this aim, a novel method based on experiment...
Numerical methods have become useful tools for predicting vehicle mobility performance on granular terrain. However, due to the large number of soil particles and complex contact search in tire-granular terrain simulation, time-consuming calculation has become the most critical problem restricting the application of these methods. In this study, an...
As the key part of the train bogie, the rolling bearings with pedestal looseness will directly affect the vehicle running safety and smoothness. For the problem of the high-speed train rolling bearing subjected to looseness faults on the fitting surface between inner ring and shaft neck, the vertical coupled dynamic model of high-speed train car bo...
