Abstract EN
Reciprocal screw theory is used to recognize the kinematic joints of assemblies restricted by arbitrary combinations of geometry constraints.
Kinematic analysis is common for reaching a satisfactory design.
If a machine is large and the incidence of redesign frequent is high, then it becomes imperative to have fast analysis-redesign-reanalysis cycles.
This work addresses this problem by providing recognition technology for converting a 3D assembly model into a kinematic joint model, which is represented by a graph of parts with kinematic joints among them.
The three basic components of the geometric constraints are described in terms of wrench, and it is thus easy to model each common assembly constraint.
At the same time, several different types of kinematic joints in practice are presented in terms of twist.
For the reciprocal product of a twist and wrench, which is equal to zero, the geometry constraints can be converted into the corresponding kinematic joints as a result.
To eliminate completely the redundant components of different geometry constraints that act upon the same part, the specific operation of a matrix space is applied.
This ability is useful in supporting the kinematic design of properly constrained assemblies in CAD systems.
