Abstract: A new approach to automated conceptual design of mechanical
system is presented by means of a state-space. At first, a state
equation is set up according to the function of a basic mechanical unit
transformed a motion between input and output terminal. Then, the input
and output characteristic vectors and the state space matrices are
defined by means of a state equation, which are corresponding to a
certain basic mechanical unit, even composite one. The conceptual design
can be extracted from the dimension design by the way. Secondly, the
state space is established in terms of the set of all characteristic
vectors for transformation units and whose properties are discussed,
such as vectors plus, constant multiplying, reversible driving, zero
vector as well as a state space matrices decomposable. However, the
mathematic model is presented and the groundwork is laid for the
conceptual design in the state space. Finally, an example is given to
show the process of conceptual design in state space.
Key words: Conceptual design Kinematic scheme design State-space CAD
