The discontinuity of impact can give rise to rich nonlinear dynamic behaviors and bring forth challenges in the modeling and analysis of this type of nonsmooth systems. The dynamical behavior of a two-degree-of-freedom vibro-impact system is investigated experimentally in this paper. The experimental apparatus is composed of two spring-linked oscillators moving on a lead rail. One of the two oscillators connected to an excitation system intermittently impacts with a spherical obstacle fixed on the thick steel wall. With different gap sizes between the impacting oscillator and the obstacle, the dynamical behaviors are investigated by changing the excitation frequencies. The experimental results show periodic, grazing and chaotic dynamical behaviors of the vibro-impact system. <\/jats:p>","DOI":"10.1142\/s0218127412501106","type":"journal-article","created":{"date-parts":[[2012,3,29]],"date-time":"2012-03-29T01:21:56Z","timestamp":1332984116000},"page":"1250110","source":"Crossref","is-referenced-by-count":14,"title":["EXPERIMENTAL INVESTIGATION OF A TWO-DEGREE-OF-FREEDOM VIBRO-IMPACT SYSTEM"],"prefix":"10.1142","volume":"22","author":[{"given":"GUILIN","family":"WEN","sequence":"first","affiliation":[{"name":"State Key Laboratory of Advanced Design and Manufacture for Vehicle Body, Key Laboratory of Advanced Design and Simulation Techniques for Special Equipment, MoE, Hunan University, Changsha, Hunan 410082, P.
