Abstract

The present work shows the three-dimensional design and the simulation of movements in a test bench to reproduce the respiratory cycle in human beings so that the useful life of a sternum prosthesis can be evaluated. A design methodology was used to identify the requirements and subsequently establish the design and selection of the elements. Among the most relevant parameters to consider in the design, the test bench is required to simulate the action of the forces on the prosthesis, which are generated during the respiratory cycle in humans, causing expansion of the rib cage and rib elevation. Additionally, the test bench is capable of applying a compression force to the thorax that produces a seat belt in an automobile to reproduce impact scenarios. The test bench has linear actuators to control the required action force and the applied displacements. Simulations results show that the test bench is capable of reproducing movements on the sternum during the respiratory cycle together with impact conditions, as well as the reliability that the test bench can be used to perform tests that require a high time.
