Dimensional variation analysis (DVA) is a computer based simulation process used to
identify potential assembly process issues due the effects of component part and
assembly variation during manufacture.
The sponsoring company has over a number of years developed a DVA process to
simulate the variation behaviour of a wide range of static mechanical systems. This
project considers whether the current DVA process used by the sponsoring company is
suitable for the simulation of complex kinematic systems. The project, which consists
of three case studies, identifies several issues that became apparent with the current
DVA process when applied to three types of complex kinematic systems. The project
goes on to develop solutions to the issues raised in the case studies in the form of new
or enhanced methods of information acquisition, simulation modelling and the
interpretation and presentation of the simulation output
Development of these methods has enabled the sponsoring company to expand the range
of system types that can be successfully simulated and significantly enhances the
information flow between the DVA process and the wider product development process.
