Input-output Equation for Spherical Four-bar Linkages

Four-bar linkages, consisting of four rigid links coupled by revolute joints forming a closed chain, can be found in a variety of applications, such as windshield wipers, pumps, window cranks, suspension systems, robots, and extraterrestrial rovers just to name a few. Designers of such mechanical systems are commonly confronted with the task of determining the appropriate link lengths that allow the system to function as optimally as possible.

The objective of my work in Austria is to develop the required theoretical knowledge by working with internationally reputed experts to derive a universal algebraic Input-output equation for spherical four-bar linkages. It is expected that the proposed work will lead to a new parametric method for not only identifying the optimal link lengths for four-bar linkages, but also identifying the optimal joint types. Hence, it will become a better computational tool for designing mechanisms that need to be extremely accurate. This is especially important if the four-bar linkage is being used for manufacturing, assembly, medical, or even extraterrestrial applications.
