Summary: We examine bifurcations of multiple limit cycles for a parametrically and externally excited mechanical system. The original mechanical system is first transformed to a Cartesian averaged equation, which is in the form of a \(Z_{2}\)-symmetric perturbed polynomial Hamiltonian system of degree 5. Then, using the bifurcation theory of planar dynamical system and the method of detection function, the bifurcations of multiple limit cycles of the system are investigated and the configurations of compound eyes are obtained.
