The purpose of this monograph is threefold. First, mathematical models
of the transient behavior of some or all of the state variables
describing the motion of multiple-link flexible structures will be
developed. The structures which we have in mind consist of finitely many
interconnected flexible ele- ments such as strings, beams, plates and
shells or combinations thereof and are representative of trusses,
frames, robot arms, solar panels, antennae, deformable mirrors, etc.,
currently in use. For example, a typical subsys- tem found in almost all
aircraft and space vehicles consists of beam, plate and/or shell
elements attached to each other in a rigid or flexible manner. Due to
limitations on their weights, the elements themselves must be highly
flexible, and due to limitations on their initial configuration (i. e.,
before de- ployment), those aggregates often have to contain several
links so that the substructure may be unfolded or telescoped once it is
deployed. The point of view we wish to adopt is that in order to
understand completely the dynamic response of a complex elastic
structure it is not sufficient to con- to take into account the sider
only its global motion but also necessary flexibility of individual
elements and the interaction and transmission of elastic effects such as
bending, torsion and axial deformations at junctions where members are
connected to each other. The second object of this book is to provide
rigorous mathematical analyses of the resulting models.
