Modeling and Analysis of Offshore Gangway under Dynamic Load

نویسندگان

چکیده

The safety transfer on the sea is threatened by wind, wave and surge loads. An offshore gangway ensures smooth safe compensating ship’s motion. In a mixed system, huge asymmetric load top of stable platform, displacement its center gravity causes it to exert large dynamic platform. A model under established in this work. Lagrange equation used establish gangway; equivalent method visualize load. platform modeled virtual work principle. Finally, accuracy mathematical was verified joint simulation. Simulation results indicate that influence load, tractive force second drive support chain 2–3 times greater than first third chains. With same excitation, 2.83 higher static

Analysis of Dynamic Properties of Piezoelectric Structure under Impact Load

Abstract: An analytical model of the dynamic properties is established for a piezoelectric structure under impact load, without considering noise and perturbations in this paper. Based on the general theory of piezo-elasticity and impact mechanics, the theoretical solutions of the mechanical and electrical fields of the smart structure are obtained with the standing and traveling wave methods, ...
