Abstract:
The principle
and method of flexible multibody system dynamics is presented.
The dynamic equation have been developed by means of Huston's
method based on Kane's equation. In which the flexible members
with general cross-section characters were divided into finite
segment models under the assumption of small strain. In order to
decrease the degrees of freedom of the system and increase the
efficiency of numerical calculation, the mode transformation has
been introduced. A typical example is presented, and the
foregoing method has been perfectly verified.
Key words:
