Abstract

Leaf spring systems are mechanical structures used to attenuate or absorb the disruptive factors such as stress, strain, deflection and deformation occurring on dynamic systems. Leaf spring systems may produce different responses to external forces depending on their geometric structures and material properties. Computer-aided analysis of leaf spring systems is crucial in determining the deformation properties and structural properties of the system with high accuracy. In this work, the 10-7, 10-5 and 8-7 multi-level parabolic steel leaf spring systems were analyzed by ANSYS Workbench 18.1 software. In the simulations, the total deformation values emerging under the pressure values of 12.5 Pa, 25.0 Pa and 37.5 Pa and the resonance frequency values for 20 different mode shapes were obtained. The simulation results represent that the highest deformations occur in 8-7 leaf spring system at all pressure values. Furthermore, as a result of the modal analyzes it was observed that the resonance frequencies of 10-7, 10-5 and 8-7 leaf spring systems were respectively occurring at the intervals of [143.17 Hz, 520.89 Hz], [143.98 Hz, 511.4 Hz] and [146.58 Hz, 525.21 Hz].
