Structural Redesign for Forced Response with Proportional Damping by Large Admissible Perturbations

A method to solve redesign (inverse design) problems of complex structures with forced response amplitude constraints is developed. The assumption is made that a structure is excited by harmonic external forces at a given frequency. The problem is to find optimum values of structural characteristics...

Zusammenfassung:	A method to solve redesign (inverse design) problems of complex structures with forced response amplitude constraints is developed. The assumption is made that a structure is excited by harmonic external forces at a given frequency. The problem is to find optimum values of structural characteristics in order to achieve a desired level of forced response at one or several locations on the structure. The method of large admissible perturbations (LEAP) is used.
