This invention discloses a method for analyzing key structural parameters in lateral airbag polishing. First, a finite element analysis (FEM) simulation is performed on the entire robotic arm and polishing head, comprehensively considering the effects of gravity, horizontal polishing reaction force, and gas pressure within the cylinder on the robotic arm's deformation. This yields the strain distribution of the robotic arm, determining the structural parameters of the adapter plate that best meet the deformation requirements. Then, a FEM analysis is performed on the polishing process of the workpiece surface. The strain distribution results are imported into path planning software and compared with the required removal function shape to select the airbag layer structural parameters that best meet the surface shape accuracy requirements for the corresponding removal surface. This method for analyzing key structural parameters in lateral airbag polishing aims to more closely approximate real-world processing conditions, providing a valuable reference for the structural design of the robotic arm and polishing head. It makes the model closer to actual processing conditions, giving the simulation results stronger practical guidance.
