Abstract

Xiangtan geely automobile production base, the author of this paper wiper washing system failure occurs, the washing ball core fracture problem of the nozzle, combined with the actual production, based on product failure reason analysis, found the ball core fracture basic appear in the winter, the temperature decrease after the plastic shrinkage, the matching of the nozzle and the spool too tight, the user without the use of special debugging tools debug copper ball, caused the ball core fracture, for this reason, put forward to increase before initial washing nozzle spray Angle 6.5 o, and adjust the structure of the nozzle core ball, the ball core from square to V groove root, enhance the strength of ball core groove, using the method of 3D modeling, According to former car washing nozzle design parameters, through the Pro/E 3D software to complete before washing nozzle and improving design of 3D model, using the finite element analysis of ANSYS Workbench before washing nozzle improvement before and after the deformation and stress distribution, the improved deformation from 0.0023643 mm to 0.0012954 mm, the improved maximum stress value from 472.87 MPa to 259.09 MPa, ultimate strength less than 300 MPa, improve the rationality of the design is verified, for enterprises to solve the quality problem, have a very good reference value.
