A Mechatronic Model for the Dynamic Analysis of the Windshield Wiper Linkages used for the Motor Vehicles

摘要

In this paper we attempt to perform the dynamic analysis of the windshield wiper linkages by using a virtual prototyping platform that includes the following software solutions: CATIA - for realizing the solid model of the system, ADAMS/View - for developing the mechanical device, ADAMS/AutoFlex - for modeling the flexible components, ADAMS/Controls & MATLAB/Simulink - for developing the control system of the mechanism. The study is approached in mechatronic concept by integrating the mechanical model and the control system at the virtual prototype level. In this way, the physical testing process is greatly simplified, and the risk of the control law being poorly matched to the real system is eliminated. The application is made for a tandem pattern double-lever wiper mechanism, which contains two four-bar spatial linkages. To drive the mechanism, a DC motor is used, the objective of the controlling process being to control the angular velocity of the motor crank.
