Investigating Chladni patterns through a tabletop point-driven Chladni setup: Simulations and experiments

Abstract

In this study, we investigated Chladni patterns numerically and experimentally using a tabletop point-driven Chladni setup for four wave numbers: 4.24 πa⁻¹, 5.14 πa⁻¹, 5.82 πa⁻¹, 6.16 πa⁻¹. Using numerical simulations (utilizing theoretical values) as basis, we were able to obtain the experimental frequencies f_exp (in Hz) as follows: 852, 1387, 1680, 1883, corresponding to the resonant modes of the thin aluminum plate (a = 200 mm, d = 1 mm).  Our work shows that it is feasible to conduct advanced resonance experiments at home using common tools. These experiments can be utilized by advanced undergraduate or even graduate students in a research-from-home setup.
