Substituting a conventional ram frame with a variants of sandwich structure

Result description

The main goal is to determine if a sandwich structure (with steel sheets as outer plates and aluminium foam as filler) is suitable for a ram in an overhead gantry. The main expected features of the new design are fewer deformations, lower weight and equal or higher natural frequencies than the current solution. A flat semi-circular sandwich structure, wrinkled (horizontal and vertical) semi-circular sandwich structure and angular-shaped sandwich structure will be implemented into the adjusted frame. It is also necessary to keep in mind the possibility of mounting the sandwich structure into the adjusted frame. Comparative analysis were done to determine if and how the new design is better than the current solution. The primary tools used for the comparison are modal analysis, static analysis and frequency response for several states.
