Design of Window Wiper for Optical Measurement Camera Applicable in Humid Environment

Design window wiper for optical measurement camera used in humid environment with temperature variation, to realize normal operation of optical measurement camera in snow and rain, in oceans and in other humid environment. Design kinematics solution and get integral structural design of the wiper according to theory of mechanism and technical conditions in combination with practical engineering application; then design fit clearance of axle hole at hinge inside the mechanism through finite element and virtual prototyping simulation and analyze impact of clearance on mechanism kinematics, conduct modeling on the wiper and perform kinematic and dynamic simulation analysis. The result has indicated that: in case initial value of axle hole at the hinge is 0.1mm, the wiper is operating normally within required variation range of the environment temperature, and can meet engineering design requirement.
