We　study　chaotic　dynamics　and　the　phase-locking　phenomenon　of　the　circular　mesh　antenna　with　1:3　internal　resonance　subjected　to　the　temperature　excitation　in　this　paper.　Firstly,　the　frequencies　and　modes　of　the　circular　mesh　antenna　are　analyzed　by　the　finite　element　method,　it　is　found　that　there　is　an　approximate　threefold　relationship　between　the　first-order　and　the　fourth-order　vibrations　of　the　circular　mesh　antenna.　Considering　a　composite　laminated　circular　cylindrical　shell　clamped　along　a　generatrix　and　with　the　radial　pre-stretched　membranes　at　both　ends　subjected　to　the　temperature　excitation,　we　study　the　nonlinear　dynamic　behaviors　of　the　equivalent　circular　mesh　antenna　model　based　on　the　fourth-order　Runge-Kutta　algorithm,　which　are　described　by　the　bifurcation　diagrams,　waveforms,　phase　plots　and　Poincaré　maps　in　the　state-parameter　space.　It　is　found　that　there　appear　the　Pomeau-Manneville　type　intermittent　chaos.　According　to　the　topology　evolution　of　phase　trajectories,　the　phase-locking　phenomena　are　found.　Copyright　©　2019　ASME.
