    "abstract": "For a preloaded impact oscillator under superharmonic excitation of order 2,\nthe Hertzian non linearity constitutes the precursor of vibroimpacts\nestablished over a wide frequency range. The theoretical study is performed by\nusing the shooting method with an arc length continuation. Experimental results\nobtained from a devoted test rig agree with theoretical ones. Particularly, the\nthreeshold level of the excitation necessary to induce vibroimpacts is\nconfirmed.",
