Abstract
Abstract. Obtaining new models of mechanical equipment to conduct mechanical
innovative design through kinematic chain configuration synthesis is an
effective method. However, in practice, due to the existence of similar
components, existing innovative design methods easily produce redundant
design schemes, which require extensive isomorphic discrimination
operations, and the design process is complex. In view of existing problems,
this study analyzes a method for discriminating between similar components of
mechanisms from the perspective of graph theory and then applies it to the
specialization of topological graphs to solve the problem of redundant design
schemes. Finally, using the innovation of a drilling rig drilling arm mechanism
as an example, 52 feasible schemes without redundancy are
obtained. This paper provides a reference for the innovation of the configuration of
planar mechanisms without design redundancy.
