We present and discuss the results of some numerical simulations dealing with wave motion in one-dimensional pantographic media, also known as beams. Specifically, analysis is carried out large displacements regime beams are modeled by using a completely discrete approach. Nonlinear vibrations induced transversal impulse studied. A simple yet efficient time-stepping scheme was used to reconstru...

It is important to establish an appropriate transporting machine on the seafloor for deep ocean mining of cobalt-rich manganese crusts, as the physiognomy of cobalt-rich manganese crusts is complex and often varies. In view of the complexity of terrain of cobalt-rich manganese crusts and huge weight that need to be supported during ocean mining, a project of the six−legged walking robot driven ...

The general concept of deployable structures based on pantographs that are deployed and stiffened by means of cables is applied to the design of the support structure for a large mesh re ̄ ector. The two main components of this structure are a cable-stiffened pantographic ring that deploys and pretensions a cable network that, in turn, provides a series of stiff, geometrically accurate support p...
