Current specifications for highway bridge design provide empirical relationships for computing lateral impact loads generated during barge collisions; however, these relationships are based on limited experimental data. To better understand and characterize such loads, dynamic finite element analysis techniques were employed to simulate vessel impact conditions never before tested experimentally. Descriptions of the methods used to model a hopper barge, bridge piers, and soil–structure interaction are given. Impact simulation results, including time histories of impact loads and barge deformations, are presented and compared with data generated using current bridge design specifications.

A dynamic finite element analysis model for cylindrical roller bearing is developed, and the complex stress distribution and dynamic contacting nature of the bearing are investigated carefully based on ANSYS/LS-DYNA. Numerical simulation results show that the stress would be bigger when the element contacting with the inner or outer ring than at other times, and the biggest stress would appear near the area that roller contacting with the inner ring. Phenomenon of stress concentration on the roller is found to be very obvious during the operating process of the bearing system. The stress distributions of different elements are uneven on the same side surface of roller in its axis direction. Numerical simulation results can give useful references for the design and analysis of rolling bearing.
