Experimental research on the effect of wing structure on Aeroelasticity phenomenon
Aeroelasticity on airplance wing has a significant on the efficiency and the safety of a flight. Therefore, the study of aeroelasticity problems is a great attention in wing design process. To analyze this, three primary subjects of aeroelastic phenomena that the examination has to focus on, which are wingtip oscillation amplitude, flutter frequency and critical flutter velocity of the wing

THE MULTI-MODE TECHNIQUE FOR AERODYNAMIC INSTABILITY ANALYSIS OF A LONG SUSPENSION BRIDGE
Flutter and buffeting responses are extremely important topics in the design of long-span bridges. This study presents the numerical analysis and numerical results of flutter and buffeting responses of suspension bridge by using the multimode analysis technique. The flutter speed of suspension bridge is evaluated by solving an eigenvalue problem. The buffeting response is carried out by using a standard random vibration analysis. The effect of...
