Dimensional control is one of the most important challenges in the shipbuilding industry.In order to predict assembly dimensional variation in hull flat block construction,a variation stream model based on state space was presented in this paper which can be further applied to accuracy control in shipbuilding.Part accumulative error,locating error,and welding deformation were taken into consideration in this model,and variation propagation mechanisms and the accumulative rule in the assembly process were analyzed.Then,a model was developed to describe the variation propagation throughout the assembly process.Finally,an example of flat block construction from an actual shipyard was given.The result shows that this method is effective and useful. 相似文献
