dc.description.abstractThis work proposes a finite element analysis and optimization for an axisymmetric rubber bumper to enhance energy absorption and impact resistance capabilities. The objective of this work is to effectively analyze the nonlinear deformation phenomenon for rubbers using the ANSYS Workbench and optimize its geometric configuration to improve its efficiency. For large deformation simulations, the Mooney-Rivlin model has been utilized to describe the behavior of rubbers, and deformation analyses using both triangulation and quadrilateral mesh patterns have also been conducted to understand their respective deformations. Analysis demonstrated that quadrilateral mesh patterns are more accurate for deformation, resulting in faster convergence. The baseline compression simulation was also carried out with a displacement limit of 20 mm, resulting in a corresponding force reaction of 117,040 N and energy absorption of about 745 J. This nonlinear force-displacement response was validated to resemble actual hyperelastic material response subjected to compression constraints. Optimization simulations for design followed modifications to essential geometric variables in the steel structure to within ±10% variations from baseline assumptions. Three optimal solutions emerged using DesignXplorer parametric analysis. The optimized design has shown about 20% improvement in energy absorption capabilities. It can therefore be asserted that controlled variation in structural geometry parameters and surface interaction properties has played a significant role in improving the efficiency of rubber buffer dampers and will continue to contribute to making energy-absorption systems durable, reliable, and maintenance-free.
