Simulation of the Assembly/Disassembly (A/D) process has a major impact on the
improvement of design activities, on determining the level of assembly
automation, as well in increasing the efficiency of the products development
process. The efficiency of such a simulation process resides in the ability to
generate and then simulate all the possible relative movements between the
components of a mechanical system. This is an important aspect for both
interactive and immersive simulations in the current context.
The proposed project was focused, in the first stage, on the theoretical
approach of the research in order to develop a kinematic model able to represent
all the valid relative movements of a target component in relation to its
surroundings, these movements creating a family of trajectories. In order to
determine the compatibility between different types of contacts and situations
in which a contact can be created/broken, a mathematical model was developed.
This model must completely define and combine of families of trajectories
associated to the corresponding contacts between different components of a
mechanical system.

In the next stage, a geometrical model was created for offering a graphical
representation of the families of valid A/D trajectories. The combination
between these two models can form, in a simulation environment, the base for
determining and displaying, in real-time, the valid movements between
components.
The main objective of the project is the development of a simulation application
for A/D process. This will give industrial engineers the possibility to perform
fast and complete analyses of assemblies, leading to the sharp decrease of the
development time of mechanical systems. Moreover, the reality level of the
simulation can be easily upgrated by using a set of haptic or natural input
devices.
