Based on advantages of microflow drive technique, a kind of vehicle windshield vibration rainwaterremoving technology was proposed. Firstly, the two dimensional (2D) mathematical model of the droplet was built by using the Stokes of long wave theory, then the 2D dropletglass model was built with the finite element analysis (FEA) software COMSOL MULTIPHYSICS. The research on relationship was carried out between symmetric low frequency vibration, the orthogonality symmetry low frequency vibration, the asymmetric frequency vibration and the symmetry low frequency vibration to movement state and speed of the droplet. The simulation results show that the droplet oscillates asymmetrically under excitation of vibration which leads to its obvious displacement macroscopically. It verifies that a windshield rainwaterremoving technology based on microflow drive technique is feasible and effective.
