The scaling of nonlinear structural dynamic systems

چکیده
A new scaling theory has appeared in the recent literature that potential to transform current approaches scaled experimentation. The introduces similitude rules hitherto did not exist and significantly extends classical definition of underpinned by dimensional analysis. Each rule is tied number experiments, theoretical terms there no limit experiments involved. focus this paper on one two applied nonlinear structural dynamics, which a field study application gives rise significant difficulties for highly behaviour common these systems means only very precise scaled-model designs can feasibly achieve acceptable outcomes. It shown how exact provided deliver precision necessary mathematically replication behaviours. demonstrated further limited scope single experiment be extended properly designed experiments. Through analysis carefully selected degrees freedom involving springs, dashpots friction, benefits are demonstrable range loading conditions. Exact confirmed providing behaviours with conformity recorded over long timescales.

Structural Identification of Nonlinear Dynamic Systems
The method of structural identification nonlinear dynamic systems is offered in the conditions of uncertainty. The method of construction the set containing the data about a nonlinear part of system is developed. The concept of identifiability system for a solution of a problem structural identification is introduced. The special class of structures S for a solution of problem identification is...
متن کاملAdaptive Fuzzy Dynamic Sliding Mode Control of Nonlinear Systems
Two phenomena can produce chattering: switching of input control signal and the large amplitude of this switching (switching gain). To remove the switching of input control signal, dynamic sliding mode control (DSMC) is used. In DSMC switching is removed due to the integrator which is placed before the plant. However, in DSMC the augmented system (system plus the integrator) is one dimension bi...
