Abstract

The invention belongs to the field of robotic grinding and polishing of composite components, and specifically discloses a method for suppressing elastic deformation and vibration of aircraft composite components during robotic grinding and polishing. The method includes: designing a first independent variable group and a first dependent variable group; carrying out a multi-parameter combined grinding process orthogonal test on the first independent variable group and the first dependent variable group to obtain the grinding force and the material removal amount Non-linear relationship; use the force-position hybrid control strategy of global variable pressure and local constant pressure to control the elastic deformation in the robot grinding process; construct the optimal stiffness and attitude relationship in the robot processing space, according to the optimal combination and elastic deformation control The final grinding and polishing process parameters are used to optimize the robot's machining trajectory and determine the grinding and polishing process parameters of the processing area. The invention can realize the effective control of elastic deformation and vibration suppression in robot grinding and polishing of aircraft composite components, eliminate grinding and polishing vibration marks, and ensure the quality of the processed surface.

Description

technical field [0001] The invention belongs to the field of robotic grinding and polishing of composite components, and more particularly relates to a method for suppressing elastic deformation and vibration of aircraft composite components during robotic grinding and polishing. Background technique [0002] Aviation, aerospace, energy and other fields have higher and higher requirements for high-end equipment performance, such as reducing structural quality and improving structural efficiency. Carbon fiber composite material (CFRP) has the advantages of light weight, high strength, designable performance, and overall manufacturing, and has become a material with great development potential and engineering application prospects. CFRP is composed of a resin matrix phase and a carbon fiber reinforced phase, which not only retains the main advantages of two-phase materials, but also complements the properties of each phase, making them correlated and synergistic, and obtaining...
