Research On Spraying Process Parameters Of Wind Turbine Blade Surface Spraying Robot

In the process of wind turbine blade production,manual spraying is still the main method.There are some problems in manual spraying,such as low efficiency,serious waste of paint,high labor cost and serious environmental pollution.The low degree of automation of spraying has seriously restricted the production of wind turbine blades.Compared with the automobile industry,the wind power industry started late,the research of automatic spraying method is relatively backward,and the related theoretical system has not yet been established.Therefore,this paper focuses on the study of wind turbine blade spraying process parameters to explore the realization of automatic spraying of wind turbine blades.The main contents of this paper are as follows:(1).Establishing the growth model of film thickness during blade sprayingFilm thickness growth model is the main tool of spraying process parameters,therefore,establishing new wind-power blades which apply to film thickness growth model is the main content of this article,is also the basis of the coating process of blade coating film effects,first of all,analyzing the spraying process and determining the main process parameters affecting the effect of spraying spraying process.Then,the advantages and disadvantages of several classical spray models are analyzed and compared.Finally,based on the ?-distribution model,the paint film distribution model suitable for wind power blade spraying was established.The selected process parameters were introduced into the newly established model as independent variables,and the influence of process parameters on the distribution of spraying coating was studied through mathematical analysis.(2).Verifying the spraying model by simulationThe simulation was carried out by ANSYS software,used to replace the spraying experiment to verify the established paint film growth model.First by using three-dimensional software blades and spray gun for 3 d modeling,and the import of 3 d models to ANSYA in early treatment,then spray the Fluid in the simulation by using ANSYS,so as to simulate the blade coating process to get the distribution of the paint film as a result,the paint film distribution results of the simulation and coating thickness model comparing with the results of distribution,verifying the coating growth model can effectively describe the film growth process,and determine according to the results of the simulation model of the coefficient.(3).Setting up an experimental platform for spraying test and the optimal parametersThe growth model of paint film is established to find out the process parameters which meet the requirements of spraying.In order to determine the optimal process parameters combination,it is necessary to set up an experimental platform to conduct spraying tests on each process parameters combination and screen out the optimal process parameters combination of spraying coating distribution.The experimental platform is built with rectangular coordinate robot as the main body.Before solving the process parameters by using the film growth model,the range of process parameters is determined according to the equipment parameters of the experimental platform and the spraying experience of manual spraying,so as to reduce the calculation.The process parameter design experiments obtained by using the film growth model sprayed,and the optimal combination of parameters was determined by comparing the spraying results.
