- Simulations showed strong agreement between the electronic and mechanical models in both single and coupled configurations.

## Abstract

This study proposes a novel electronic circuit design that accurately replicates the dynamics of a mechanical discontinuous impact oscillator characterized by hard elastic impacts. The governing equations of the circuit are systematically derived to establish its equivalence with the mechanical system. Numerical simulations are conducted for both single and coupled configurations, demonstrating a high degree of agreement between the electronic and mechanical models.
