Research and Exploration of Automatic Welding Wire Technology for Horn

With the development of science and technology,the electronic component industry has become more and more extensive,covering circuits,electrical and electrical systems from small to large.Many of these parts have very high requirements for the production process,and the production process requires a certain amount of workshop space.In the traditional production process,soldering is mainly manual welding.With the development of intelligence,impersonality and automation,the design of electronic products will gradually move towards intelligence.In this process,the application and promotion of welding technology is essential.In order to ensure the production of automatic products,this paper studies and discusses the function control problems and solutions of the soldering machine.Loudspeaker(commonly known as loudspeaker)is one of the most widely used electronic devices.With the development of the electronic industry and the change of the market environment,major manufacturers are developing new products to meet the market demand and product performance.In order to meet the needs of a large number of high reliability electronic products with different structures now and in the future,automatic welding technology is required to ensure that the welding quality and reliability have certain advantages.

Cost-Based Research on Energy Management Strategy of Electric Vehicles Using Hybird Energy Storage System

This paper uses the minimization and weighted sum of battery capacity loss and energy consumption under driving cycles as objective functions to improve the economy of Electric Vehicles(EVs)with an hybrid energy storage system composed of power batteries and ultracapacitors.Furthermore,Dynamic Programming(DP)is employed to determine the objective function values under different weight coefficients,the comprehensive cost consisting of battery aging and power consumption costs,and the relationship between the hybrid power distribution.We also evaluate the real-time fuzzy Energy Management Strategy(EMS),fuzzy control strategies,and a strategy based on DP using the World Light vehicle Test Procedure(WLTP)driving cycle and a synthesis driving cycle derived from New European Driving Cycle(NEDC),WLTP,and Urban Dynamometer Driving Schedule(UDDS)as examples.Then,the proposed strategy is compared with the fuzzy control strategy and the strategy based on DP.Compared with fuzzy energy management strategy(namely FZY-EMS),the proposed EMS reduces the battery capacity loss and system energy consumption.The results demonstrate the effectiveness of the proposed EMS in improving EV economy.
