Abstract | Collision detection and response between the block model in shipbuilding simulation are one of the most difficult issues in dynamic analysis. The existing collision programs are not appropriate to be applied in this domain because the model has unclosed meshes and very sharp edges. Therefore, this study proposed a position difference method to detect collision between unclosed meshes. This method calculates the intersection between the previous and current positions of the two meshes. Moreover, because the shape of the colliding body in the shipbuilding industry has too many meshes, it takes too much time to detect collision between two bodies. To increase performance, this study adopted a boundary volume hierarchy which is a kind of space-partitioning algorithm and exclusion boxes which exclude meshes inside boxes. For the collision response, this study derived a force-based method based on the non-interpenetration constraint to calculate the collision normal and tangential forces. This method can be applied to the multibody system and to consider material properties such as restitution coefficient and softness. As a result, it is successfully applied to the dynamic analysis of LPG tank erection by using a floating crane. The collision force between the tank and the hull structure is calculated due to the motion of the floating crane induced by environmental loads. |
