Other AbstractThe invention relates to a method for automatic control over laser shock peening. The method comprises the following steps that a part analysis model is built in mechanical analysis software according to the machining requirement, and residual stress distribution is obtained; residual stress distribution is guided into CAE analysis software, and a machining motion track acting on the surface of a part is automatically generated; meanwhile, technological parameters corresponding to a laser shock wave pressure set value are selected by an industrial personal computer according to the relation between laser shock wave pressure and laser peening technological parameters; the machining motion track and the technological parameters are guided into the mechanical analysis software for simulation so as to obtain a strain value after machining simulation; and if the strain value is within the set range, the technological parameters are sent to a laser device through the industrial personal computer, the machining motion track is sent to a robot, and automatic laser machining is achieved. By means of the method, laser shock peening of an integral blade disc can be achieved, quantitative precise control over residual stress is achieved, the service life of the integral blade disc is effectively prolonged, and the foreign matter damage resisting capacity of the integral blade disc is effectively improved.
