Spatial Control of Functional Response in 4D-Printed Active Metallic Structures
We demonstrate a method to achieve local control of 3-dimensional thermal history in a metallic alloy, which resulted in designed spatial variations in its functional response. A nickel-titanium shape memory alloy part was created with multiple shape-recovery stages activated at different temperatures using the selective laser melting technique. The multi-stage transformation originates from di...
متن کاملSEMI-ACTIVE NEURO-CONTROL FOR MINIMIZING SEISMIC RESPONSE OF BENCHMARK STRUCTURES
This article presents numerical studies on semi-active seismic response control of structures equipped with Magneto-Rheological (MR) dampers. A multi-layer artificial neural network (ANN) was employed to mitigate the influence of time delay, This ANN was trained using data from the El-Centro earthquake. The inputs of ANN are the seismic responses of the structure in the current step, and the ou...
متن کاملActive Control in Structures
In this paper the application of control theory to structural engineering has been presented from a structural engineering perspective. The objective of this paper is to summarize key steps that are required to design an active control system for a structure. Total acceleration feedback with H2/LQG controller is used in this paper. The structural control device is made of tendon/pulley system. ...
متن کاملActive Control of Structures
In recent years a large large amount of work on the active control of the flexible structures has been done. The concrete engineering problems that motivate this study come from very different fields: aerospace, structures, meteorology, nanotechnology, etc. An overview can be found in the book of Fuller, Elliot and Nelson [5]. The problem of active vibration control (AVC) can be set in the fram...
متن کاملSolutions : Active Control of Structures
0.1 Challenge 1 If we consider that G(x, t) and W (x, t) are harmonic functions in time, then there exist functions g(x) and w(x) such that G(x, t) = g(x) cos(ωt) and W (x, t) = w(x) cos(ωt). Reeplacing these two expressions in the problem (1), we have that −ω2w(x) cos(ωt)− c2w′′(x) cos(ωt) = g(x) cos(ωt), which implies that −ω2w(x) − c2w′′(x) = g(x). On the other hand, the function W (x, t) sa...
