Robust Optimal Design of Beams Subject to Uncertain Loads
Optimality conditions are derived for the robust optimal design of beams subject to a combination of uncertain and deterministic transverse and boundary loads using a variational min-max approach. The potential energy of the beam is maximized to compute the worst case loading and minimized to determine the optimal cross-sectional shape which results in coupled nonlinear differential equations f...
متن کاملOptimal Design of a Beam under Uncertain Loads
Optimal design of beams subject to a combination of uncertain and deterministic transverse loads is presented using a min-max approach. The compliance of the beam is maximized to compute the worst case loading and minimized to determine the optimal cross-sectional shape. The uncertain component of the transverse load acting on the beam is not known a priori resulting in load uncertainty subject...
متن کاملRobust Iterative Learning Controller Design for 2d Uncertain Linear Systems Subject to External Disturbances
This paper presents a robust iterative learning control (ILC) for a class of two dimensional (2D) linear systems with parametric uncertainty and considerable disturbances. The proposed control law is iteratively updated to guarantees the robust stability. Based on H∞ setting, sufficient conditions for robust monotonic convergence of the proposed scheme are presented in terms of linear matrix in...
متن کاملOn Robustness Criteria and Robust Topology Optimization with Uncertain Loads
We propose a new algorithm for the solution of the robust multiple-load topology optimization problem. The algorithm can be applied to any type of problem, e.g., truss topology, variable thickness sheet or free material optimization. We assume that the given loads are uncertain and can be subject to small random perturbations. Furthermore, we define a rigorous measure of robustness of the given...
متن کاملOptimal Nonlinear Energy Sinks in Vibration Mitigation of the Beams Traversed by Successive Moving Loads
Optimal Nonlinear Energy Sink (NES) is employed in vibration suppression of the beams subjected to successive moving loads in this paper. As a real application, a typical railway bridge is dynamically modeled by a single-span beam and a traveling high-speed train is simulated by a series of successive moving loads. Genetic algorithm is employed as the optimization technique and optimal paramete...
