Abstract

The invention belongs to the field of grinding and polishing machining of a composite material component by a robot, and particularly discloses an elastic deformation and vibration inhibition method for grinding and polishing machining of the airplane composite material component by the robot. The method comprises the following steps that a first independent variable group and a first dependent variable group are designed; a multi-parameter combined grinding machining orthogonal test is carried out on the first independent variable group and the first dependent variable group to obtain a nonlinear relationship between the grinding force and the material removal amount; a force-position hybrid control strategy of global variable pressure and local constant pressure is adopted to control elastic deformation in the grinding machining process by the robot; and an optimal rigidity and posture relation in the machining space of the robot is constructed, a machining track of the robot is optimized according to optimal combination and grinding and polishing machining process parameters after elastic deformation control to determine grinding and polishing machining process parameters of a machining area. According to the elastic deformation and vibration inhibition method for grinding and polishing machining of the airplane composite material component by the robot, effective control ofthe elastic deformation and vibration suppression in the grinding and polishing machining process of the airplane composite material component by the robot can be achieved, grinding and polishing machining vibration lines are eliminated, and the machined surface quality is guaranteed.

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...
