Laser heating power effect synergy variable-stiffness weight-losing light-weight method and system

Abstract

The invention discloses a laser heating power effect synergy variable-stiffness weight-losing light-weight method and system. The method includes the following steps that original data X of a part are measured; the part is subject to light-weight machining; a parameter X0 of the part obtained after light-weight machining is measured; a machining parameter Y0 of a laser for first-time laser quenching is analyzed and measured; nth-time laser quenching is carried out on the first surface of the part; a parameter Xn of the part obtained after laser quenching is detected; the data Xn and Xn-1 are compared and analyzed, the machining parameter of the laser is adjusted according to the relative difference value and the error of the Xn and Xn-1, the adjusted machining parameter is recorded and saved into data Yn; and whether the error of the data Xn and the data X is smaller than a preset error value or not is judged, machining is finished if the error of the data Xn and the data X is smaller than the preset error value, and the quenching step is repeatedly executed if the error of the data Xn and the data X is not smaller than the preset error value. By means of the method, the weight of a part structural member in the aviation field can be effectively reduced, consumable items are reduced, and reduction of properties such as hardness, strength and stiffness of the part structure is avoided.

Description

technical field [0001] The invention relates to the field of aeronautical structural parts processing, in particular to a method and system for reducing weight and weight through laser thermodynamic effect and variable stiffness. Background technique [0002] With the advancement and development of science and technology, it is not difficult to launch aerospace equipment into space in fields such as aerospace with special requirements for fatigue-free life. In the low-earth orbit of the International Space Station flying around the earth, the gravitational force is almost as strong as that on the ground. If The International Space Station is stationary relative to the Earth, so it will fall back to the ground in a free fall. If you want to stay in orbit, you must fly at a speed of at least 8 kilometers per second, so how to ensure the flight speed becomes a problem. problem. [0003] Under the condition that the overall structure of aerospace equipment remains unchanged, th...

[0007] However, in the prior art, due to the different roughness of the surface of the processed material, the absorption rate of the laser on the surface of the material will be different during the laser processing, while the processing parameters of the laser are unchanged, so the surface of the material after processing Different hardening zone widths, which affect the properties of the workpiece surface
