In recent years, flat wipers are gradually adopted in the industry of transportation due to the rather simple structure than the standard wiper. A procedure is developed to evaluate the appropriateness of the geometry of a metallic flexor, one of major components of the flat wiper, in this study. The flexor is compressed against a level surface and the corresponding pressure distribution under the flexor is measured by using piezoelectric sensors. Several geometry parameters built in a three-dimensional flexor model are investigated to appraise their influences on the corresponding pressure distribution. A process automation software linked to a computer-aided drawing and a finite element analysis commercial packages are utilized, based on the self-defined performance index, to pursue parameter arrangements proper for the pressure distribution. The present procedures are next applied to a curved windshield glass to evaluate optimized flexor geometries at various locations. Appropriate flexors for the windshield glass are then determined and practically sampled. Dynamic wiping simulations of the integrated flat wiper on the windshield glass are furthermore carried out and the pressure distributions over the sweep range are estimated. Wiping capabilities of the wiper are experimentally observed and compared with the associated numerical results.
