| Sažetak: | This work presents the evaluation of the influence of the assembly preloads and the number of leaves on the energy dissipation phenomenon of a leaf spring through a parametric study. The study consisted of estimating the amount of energy dissipated by varying the number of spring leaves and preloads, through the use of clamps, both numerically and experimentally. Through compression tests, the behavior of the spring was observed through a force-displacement relationship. The strain energy and total frictional dissipation were obtained by integrating the hysteresis curve. Numerical modeling was performed with the commercial finite element package Abaqus in a quasi-static state. The results obtained show that the preloads influence the energy dissipation of the spring, increasing mainly when these are implemented with a greater number of leaves, up to 189%. With these results, it is possible to propose a configuration that allows the greatest amount of energy to be dissipated passively and, consequently, to improve the damping of the vehicle in reference to the commercial spring. |
