Abstract:Aimed at the new requirements of the spraying efficiency and surface quality of the aviation manufacturing industry in our country at present stage, combined with the spray characteristics of a certain type aircraft vertical tail model, a trajectory planning algorithm was presented, and the specific function expression of the algorithm was given. The robot spraying motion control simulation was implemented by using the module of DELMIA/IGRIP, and sample coating surface quality parameters were obtained in early spray test, which provided certain theoretical basis for the subsequent actual spraying and spraying robot off-line programming control. The experimental results show that the trajectory planning algorithm is reasonable, and has certain actual application value.
