Abstract

Abstract The boneless reed curve of the car wiper has geometric nonlinearity and variable curvature characteristics. In order to design a geometric curve that satisfies the working performance of the boneless wiper reed, the inverse solution function item in the finite element simulation and the addition of appropriate boundary conditions are used to solve the geometric curve of boneless wiper reed before it is stressed, and verify the accuracy through the known actual reed. To prepare for actual processing, the geometric characteristic parameters of different curves are extracted on the basis of the above. Based on the small deformation linear deflection equation of the beam obtained by the superposition method, a large deformation correction item is added to correct the small deformation equation, and the influence of the length of the wiper buckle on the curve is considered. Construct a correction equation including load requirements, reed geometric dimensions, and material parameters to fit the geometric curve of the boneless wiper reed, so as to provide certain guidance for actual production.
