Investigation on energy consumption modeling analysis method of laser cladding system
摘要
Abstract
Aiming at the problem that the energy consumption mechanism of additive manufacturing process is complex and the energy consumption is difficult to predict,the energy consumption modeling analysis method of laser cladding system is studied.According to the working principles and characteristics of energy consumption,the laser cladding system is divided into five subsystems:laser generator system,cooling system,mechanical arm control cabinet,powder feeding system and auxiliary system.Each subsystem energy consumption model is obtained by theoretical analysis and experimental studies.The total energy consumption model can be obtained by aggregating the five subsystem energy consumption models.Then the experiment of processing a 316L stainless steel specimen is conducted as an illustrative example.The energy consumption model and the specific energy consumption are analyzed.The results show that the errors of the energy consumption and the specific energy consumption between predictive values and real measure values are 1.37% and 2.17% respectively,which verify the validity of the model.The model can be used for predicting laser cladding system energy consumption,improving process routes,and implementing the green development.Also,the proposed approach can provide reference for studying energy consumption issues of other additive manufacturing technologies.关键词
