The application relates to the technical field of
metal material surface strengthening, in particular to a self-adaptive
laser shock
peening method and
system based on light path dynamic regulation and real-time monitoring. The method comprises the following steps: preprocessing and constructing a digital twin model, dividing different curvature
processing areas and presetting
peening parameters; dynamic focusing
galvanometer and beam shaper are cooperated to ensure that
laser is vertically incident and the spot shape and area are constant; an adjustable
nozzle adaptively supplies a constraint layer, an
ultrasonic sensor real-timely monitors water film thickness and feeds back adjustment; a high-speed
spectrometer and an
acoustic sensor collect multiple signals,
plasma parameters are inversely deduced to evaluate the shock effect, energy compensation is triggered when an
abnormality occurs, and closed-
loop control is formed. The
system corresponds to three-dimensional scanning, digital twin
processing, dynamic beam adjustment, constraint layer supply,
quality monitoring module and a
control system. The method and
system are suitable for complex curved surface workpieces, improve
peening uniformity and stability, and are suitable for high-precision peening
processing of materials such as
titanium alloy.
