FE Simulations of Mounting of an Anisotropic Work Piece Material to Reduce the Effects of Vibration
(2021) MMTM05 20211Production and Materials Engineering
- Abstract
- Optical cavities should be designed to be insensitive to vibration in all directions. The study of the behavior of the material used to develop an optical cavity is vital for the cavity to be insensitive in all orders. In this project, we are using Abaqus to generate a FE model of an optical cavity and its mountings via support points in order to investigate the effects of vibration in different directions during machining. In any machining operation, mounting the workpiece is critical, and it is one of the most critical factors in reducing vibration, by varying mounting orientations.
The work begins with the recreation and development of a FE model in Abaqus with appropriate boundary conditions as in the reference paper. To achieve the...

The work begins with the recreation and development of a FE model in Abaqus with appropriate boundary conditions as in the reference paper. To achieve the desired results, various load and boundary conditions were simulated. Material properties were varied for the same model with obtained boundary and load conditions, and differences in deformation and stress patterns are presented in this paper.
The optimal mounting position was chosen to investigate the anisotropy material behavior for different orientations by varying the stacking directions. The effects and sensitivity of vibrations due to external loading on optical cavities for different anisotropy material orientations were investigated. Finally, modal analysis was performed for the selected model properties and mounting position to investigate the system's natural frequencies and behavior. (Less) - Popular Abstract
