Subspace Identification of a 5 MW Reference Wind Turbine,d control. Simulating their dynamic response requires numerical solvers, and the use of frequency-domain techniques is prohibited, which eliminates many commonly used engineering techniques. Subspace identification is a convenient method to approximate a complex, nonlinear system with a linear model

Dynamic Analysis of Complex Mechanical Structures Using a Combination of Numerical and Experimental Techniques,res (e.g., a vehicle superstructure supported on a given chassis). The basic idea is to first measure the acceleration time histories at the connection points of the vehicle superstructure with its suspension system and use them subsequently as a base excitation in a finite element model of the supe

Some Non-conventional Boundary Conditions (From Marshmallows to Plungers: Who Would Have Guessed),cult to implement than others, but ultimately the effect of the boundary condition on the actual modes of the system are of concern. An expensive setup may not be any better than an equivalent, inexpensive “Rube Goldberg” approach. In lieu of an expensive setup, a low cost, easily deployed configura

Measurement of Vibration Resulting from Non-contact Ultrasound Radiation Force,there are delicate structures where it is desirable to excite vibrations without physical contact. The ultrasound radiation force provides a noncontact excitation method resulting from the nonlinear interaction of sound waves scattering from an object. The incident ultrasound consists of sine waves
