Abstract�� A simpler and more accurate of propellant grain calculation which is based on SolidWorks API interface and Visual Basic has been developed for grain embedded metal wires. It can build parametrical model for grain embedded metal wires automatically and distill burning surface which occurs during burning process by SolidWorks API. As a result of the relation between burning surface and propellant thick, the interior ballistic performances can be simulated. The result shows that this calculation method is feasible and has a better precision. The calculation results are in good agreement with experiment results. It can also simulate the burning process of this type grain and be satisfied with actual engineering calculation. This software is a useful tool for difficult propellant grain calculation and propellant grain design with this type grain.
