Implant System

This study aimed to improve the micromotion of a Semados dental implant system subjected to dynamic chewing loads. Micromotion of the Semados dental implant system with basic dimensions was obtained using dynamic finite element analysis, and five parameters of the implant were selected as the control factors to be improved. A uniform design method was employed to construct a set of experimental simulations. Next, for each experimental simulation, the dynamic finite analysis package ANSYS/LS-DYNA was employed to simulate the behavior of the Semados dental implant model subjected to dynamic chewing loads and then determine the maximum micromotion of the cortical and cancellous bones. Finally, the best design of the experimental simulations that caused the smallest amount of micromotion was selected as the improved design version. Compared to the original design, which experienced micromotion of 74.53 μm, the improved version experienced micromotion of 45.41 μm. The rate of improvement was 39.1%.

Cylindrical Roller

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.
