Research advance in the rigid-body-spring model dynamics
Abstract:In this paper, the researches of rigid-body-spring networks in structural concrete, three-dimensional crack, offshore platform, board structure, conical disk spring for the rod string absorber are summarized. The vibration research on the pipage in ocean platform is introduced. The conclusion is that using well rigid dynamics and spring dynamic characteristic to study large structure dynamics problem is feasible and resultful under the condition of no well-rounded appropriate elastic dynamics theory. Study the dynamic of rigid-body-spring in fluid is an important open subject.
