Study on the Kinematics of Windshield Wiper Mechanisms of a Car by using an Engineering Software

Abstract

The objective of the article is to make a synthesis of kinematic models of wipers with one and two blades operating on the windshield of a car. With selected windscreen sizes of 1.5x1.3x0.8  with an area of 1.12  and selected blade sizes 0.4; 0.5; 0.55; 0.6; 0.65; 0.7 , the area covered reaches up to 63%. In the common types of assembly the blade operation angle reaches up to 88°. Diagrams of the analyzed mechanisms of work of the common two blades are shown and dependencies about the operation angles of the blades have been derived. Percentage relations of covered area depending on the assembly of one- and two-blade mechanisms have been presented in a table format.
