Analyzing and Optimizing Multibody Systems

Analyzing and Optimizing Multibody Systems*

Optimization of holonomic as well as non-holonomic multi body systems is presented as a nonlinear programming problem that can be solved with general-purpose optimization codes. The adjoint variable approach is used for calculating design derivatives of a rather general integral type performance measure with respect to design parameters. The resulting equations are solved by numerical integrati...

Analyzing and Optimizing the Linux Networking Stack

It is well known the Linux Operative System provides a support so complete and effective to networking functionalities, to be widely used in many advanced fields, like, among the others, software routers and GRID architectures. Notwithstanding the arising popularity and the continuous development of the Linux Operative System, there is no clear indication about the maximum networking performanc...

The Comparison of Direct and Indirect Optimization Techniques in Equilibrium Analysis of Multibody Dynamic Systems

The present paper describes a set of procedures for the solution of nonlinear static-equilibrium problems in the complex multibody mechanical systems. To find the equilibrium position of the system, five optimization techniques are used to minimize the total potential energy of the system. Comparisons are made between these techniques. A computer program is developed to evaluate the equality co...
