- The main objective of the work presented in this chapter is to identify the working scheme of the brace’s structure, subsequently enabling identification of the possibilities of potential brace design optimization. This chapter presents the results of numerical simulations concerning a Boston-type orthopedic brace with the use of the finite element method (FEM) in the Ansys Workbench environment. Reverse engineering methodology was employed to develop the geometric model, based on the results of digitization performed by an optical 3D scanner. To experimentally verify the FEM model, a test stand for measurement of the brace’s field of displacements, equipped with a laser electronic speckle pattern interferometer (ESPI), was used. Special attention was paid to representing the loads and boundary conditions of numerical simulations in experimental tests. Ultimately, the relative difference between numerical and experimental results in displacements in the central part of the brace’s front wall did not exceed 0.9%. The force flow trajectories characteristic of the brace’s shell were determined using the experimentally confirmed FEM model, revealing the overall way of its operation. The main areas of the brace carrying loads correcting the spine and sites performing little effort, from the perspective of their participation in the brace’s fundamental therapeutic application, were identified. The conducted analysis is universal in nature and can be adapted to other types of orthopedic braces. The results obtained allow for the proposal of methods for mechanical optimization of the brace’s design.
