Development of an Optimum Design Program for Wiper Linkages

An optimization program for the design of wiper linkages is developed to minimize jerky motion while satisfying design constraints on kinematic and torque performances, mobility condition, and packaging. The lengths/orientations of links and the position of a driving motor are selected as design variables. In our optimum design program for wiper linkages, an optimization module interacts with an analysis module which calculates kinematic and force/torque properties, until convergence.

The optimization results of a particular wiper linkage are presented to illustrate the effectiveness of the program developed.
