| Abstract Scope |
The design of lighter, more effective lattice structures for shock absorbers is enabled by additive manufacturing. However, the choice of the optimal lattice structure for a given application is not an easy task, given the complexity of the mechanical response in the microstructural level and the different ways it can affect the behavior of the component. The use of multi-scale finite element simulations provides an accurate and practical alternative for testing and comparing different designs. This work focuses on the modelling and execution of such multi-scale simulations for different types of shock absorbers. In each case, different lattice structures, with varying shapes, thicknesses and densities are compared. Results are validated with experimental data from the literature and confirm the predictive ability of the simulations. Moreover, in some of the cases, enhanced designs are proposed and numerically tested, supporting the use of the simulations as a means of improving design. |
