Title: Robotic welding in large-scale ship hull construction
Abstract: With the rapid development of robotic technology, industrial robots have been widely used in welding engineering, thanks to their high efficiency, good stability, and high precision, which plays an irreplaceable role in the transformation of labor-intensive industries to automated production. This presentation will introduce the robotic welding in large-scale ship hull construction for Dalian Shipbuilding Industry Co affiliated DSIC Equipment Manufacture Co., Ltd. A robotic welding system is developed by integrating the industrial robots, gantry system, flexible computer-aided manufacturing system, etc. Prior to real applications, simulation of thermal effects, path planning, and operation scenarios are carried out to find the optimal manufacturing processing. In order to improve the welding precision, an approach of offline programed error compensation for the industrial robots is proposed, which can effectively reduce the positioning error. Finally, industrial management software is developed to build the communications among the protocols of various mechatronic devices, and to send/receive the commands between the integrated manufacturing system and production requirements.

Title: Research on life prediction of supercapacitor based on improved long-term and short-term memory neural network
Abstract: Long short-term memory neural network optimized based on hybrid genetic algorithm is proposed to predict the remaining useful life of supercapacitors. First, determine the input variables of the deep neural network. By analyzing the structural characteristics between the electrode and the solution, and the characteristics and laws of the movement of internal charges, the energy storage mechanism of the supercapacitor is studied, and the influencing factors of the supercapacitor performance aging are obtained. The input variables of the neural network model are determined according to the influencing factors of the performance aging of the supercapacitor, in order to achieve accurate prediction of the remaining useful life of the supercapacitor. Secondly, two tests are designed to obtain supercapacitor aging data. A large amount of data is the basis of high precision for life prediction, to fully reflect the aging condition of the power supply under different running environment, this paper uses different charge and discharge strategies based on different temperatures and voltages to perform a steady-state cycle life test and Hybrid Pulse Power Characteristic test on the supercapacitors to make the measured data more real and effective.
