Simulation Study on the Virtual Assembly Based on CATIA

Taken a manned submersible as an example,it introduced a virtual assembly method based on the CATIA.Using the CATIA to model the three-dimensional simulation according to the design plan,to assemble all systems of the submersible in the virtual space,it not only verify the correctness of the design,but also make a more rational about the assembling of equipment and devices,but also conducive to determine the location of the submersible inner tube and wire penetrating.
