Research for separating motion-induced forces and gust forces acting on rectangular sections in turbulence flow

Abstract

In flutter analysis, Signature turbulence, gust forces and motion-induced forces acting on structures are often treated by summing so far. But it’s beneficial to analyze focusing on motion-induced forces since it’s conceivable that only motion-induced forces affect vibration of structure. So, this research aimed to add method for extraction of motion-induced forces as a trial. As a result, motion-induced forces can be separated from the entire forces indeed, and evaluations by both seem almost consistent. However, this theme needs to consider deeper continuously.
