The invention discloses an
aviation part
quality optimization management method and
system based on
data analysis, and relates to the technical field of
quality management, and the method comprises the steps: collecting an
acoustic emission signal and an
eddy current signal in the SLM forming process of an
aviation part through a multi-
modal sensor, and generating a multi-
modal data set; key features are extracted from the multi-
modal data set, multi-dimensional principal component feature vectors are obtained through fusion, a
phase space is constructed,
dynamic feature parameters are calculated, and a nonlinear dynamic model is constructed; inputting a multi-
modal data set acquired in real time into the nonlinear dynamic model, predicting a dynamic characteristic parameter evolution trajectory, triggering quality
abnormality early warning in combination with a
critical threshold, and determining a quality
risk level according to a supercritical threshold amplitude; and calling a pre-stored
laser parameter regulation and control scheme according to the quality
risk level, adjusting the mode and power of the
laser beam, and monitoring the regulation and
control effect in real time until the state of the
molten pool is recovered to be stable, so that high-precision
quality optimization and
active control in the SLM forming process of the
aviation parts are realized.
