  Inspired by recent advances in observational astrophysics and continued
explorations in the field of analog gravity, we discuss the prospect of
simulating models of cosmology within the context of synthetic mechanical
lattice experiments. We focus on the physics of expanding Universe scenarios
described by the Friedmann-Lema\^itre-Robertson-Walker (FLRW) metric.
Specifically, quantizing scalar fluctuations in a background FLRW spacetime
leads to a quadratic bosonic Hamiltonian with temporally varying pair
production terms. Here we present a mapping that provides a one-to-one
correspondence between these classes of cosmology models and physical
mechanical oscillator systems. As proof-of-principle, we then perform
experiments on an actual synthetic lattice system composed of such oscillators.
We simulate two different FLRW expansion scenarios driven by inflationary dark
energy- and matter-dominated Universes and discuss our experimental results.
