This paper shows how pure travelling waves in cascaded, lumped, uniform, mass-spring systems can be defined, established, and maintained, by controlling two boundary actuators, one at each end. In most cases the control ...
This paper describes how pure
travelling waves in cascaded, lumped, uniform, mass-spring systems can be
defined, established, and maintained, by controlling two boundary actuators,
one at each end. In most cases the ...
For many good reasons there is growing interest in ways to allow parallel processing of multibody dynamics problems. Some recent approaches include “Domain Decomposition” and “Divide and Conquer”. This paper explores a new ...
A new method is presented to determine the mode shapes and frequencies of uniform systems consisting of chains of masses and springs of arbitrary number with arbitrary boundary conditions. Instead of the classical eigenproblem ...
More than 85% of reported brain traumas are classified clinically as “mild” using GCS; qualitative MRI findings are scarce and provide little correspondence to clinical symptoms. Our goal, therefore, was to establish in-vivo ...
A companion paper considers travelling and standing waves in cascaded, lumped,
mass-spring systems, controlled by two boundary actuators, one at each end,
when the system is uniform. It first proposes definitions of waves ...

this conference considers travelling and standing waves in cascaded, lumped,

Flexible robots are frequently represented by lumped models. In the mechanics of lumped systems, wave concepts have been avoided, for good reasons, generally. In the control of lumped flexible systems, however, wave concepts ...
The need to achieve rapid and accurate position control of a system end-point by an actuator working through a flexible system arises frequently, in cases from space structures to disk drive heads, from medical mechanisms ...
Wave-based control (WBC) of underactuated,
flexible systems considers actuator motion as launching a mechanical wave into
the flexible system which it then absorbs on its return to the actuator. The launching
and absorbing ...
An elegant, generic solution is presented to the problem of point-to-point control by a single actuator of a remote load through an intermediate flexible system, modelled by a system of lumped masses and springs. It is ...
This paper considers cascaded, lumped, flexible systems, which may be short and non-uniform, which are driven by an arbitrarily moving boundary. Such systems exhibit vaguely wavelike behaviour yet defy classical wave ...
