Abstract

Optimal design of multibody systems is of primary importance to researchers working in various fields. The goal of the paper is to present a novel Hamiltonian based approach for finding design sensitivities of multibody systems (MBS) through the use of direct differentiation method. The total derivatives of Hamiltonian equations of motion (EOM) based on the augmented Lagrangian in terms of the design are determined in the text. An algorithm for the evaluation of a gradient of an objective function is also delivered. Sample test case is presented that demonstrates the validity of the proposed approach.
