#92 More Modal Fun - “Forced Vibration” at One Point

Matthias Rath, Stefan Bilbao

The question, if a vibrating object can be forced to follow a given movement profile at one point forms a case of an inverse problem. It is shown that for a specific setting, the one of an object described by modal data, this question may be solved by a newly developed method. The new technique has several strengths, such as allowing to compute modal data for the constrained scenario and forming a basis for precise and stable simulations. The latter potential is shown at a short example, a stiff string being hammered against a fixed board a hammer of infinite mass.
