Curved Plates Positioning and Flexible Brackets Control in Virtual Shipbuilding Simulation
Flexible bracket system is a kind of adjustable fixture with many movable pillars and adaptive to curved plates with various sizes and shapes, thus facilitating fast and precise position or assembly of the curved plates. The purpose of this work is to simulate the control process of flexible brackets to fit different curved plates automatically in virtual environment, thus helping process engineers preview the assembly results, adjust and determine the configuration and controlling scheme of the flexible brackets. The proposed methods for flexible bracket simulation are composed of four steps. First, build a virtual environment of the shipbuilding scene. Second, calculate the pose of the digital curved plate model. Third, optimize the pose and layout of the flexible brackets to fit the curve plate. Last, calculate and optimize the control parameters of the flexible brackets. Our virtual simulation method for flexible brackets reduces the workload for pose adjustment and reconfiguration during the real assembly process, contributing higher precision and efficiency for the curved block building.
