Optimum Design of an Archery Twin Round-Wheel Compound Bow

In this article, an optimization of a twin round-wheel compound bow is presented. Based on a previously published mathematical model of the kineto-elastic system, an objective function is introduced to maximize the stored potential energy in the compound bow limbs. The optimized design of the compound bow shows an increase in the potential energy stored for the same drawn distance. However, a slightly higher force is required and the initial position of string is slightly closer to the riser. Two different optimality criteria are also discussed.
