Flexure bearings under plastic deformation for mechanical energy absorption
A flexure bearing is a mechanical component designed to enable controlled flexing or deformation, resulting in low-friction movement. It typically consists of thin, flexible materials and is used in precise applications, such as optical systems, robotics, and aerospace, for motion control. Due to th...

| Sumario: | A flexure bearing is a mechanical component designed to enable controlled flexing or deformation, resulting in low-friction movement. It typically consists of thin, flexible materials and is used in precise applications, such as optical systems, robotics, and aerospace, for motion control. Due to their high energy absorption capacity and ease of replacement, flexure bearings are also ideal for use in safety systems, such as seismic events and impact protection. This study investigates the behavior of disc-shaped flexure bearings under plastic deformation. Two specific geometries were modeled and simulated using finite element analysis, fabricated, and subjected to tensile tests, validating the accuracy of the model. Additionally, further geometries were simulated, revealing different energy absorption curve profiles for devices with identical dimensions and similar absorption capacities. This allows for the selection of the most suitable disc based on desired performance characteristics. |
