Abstract The vibration characteristics of the submerged-propeller shaft coupling system are studied in this paper. Firstly, Based on fluid structure interaction theory acoustics wave equation, analysis model propeller-shaft under water is established and computed. And analysed by comparing system. results show that natural presents complicated strong or weak characteristics. Comparing frequenci...

Abstract Wire rope is an element often used in transportation infrastructure and systems such as bridges, elevators, ropeways, funiculars so on. Generally, wire ropes require a high level of safety because they suspend heavy important components roadways cages cabins ropeways funiculars. In addition to dead loads like roadways, are subjected dynamic caused by earthquakes, wind moving cars, etc....

Composite structures are often used in aircraft because of the advantages offered by a high strength to weight ratio. However, the acoustical properties of these light and stiff structures can often be less than desirable resulting in high aircraft interior noise levels. In this paper, measurements and predictions of the transmission loss of a curved honeycomb composite panel are presented. The...

Abstract: In the present article, a semi-analytical technique to investigate free bending vibration behavior of axially functionally graded non-prismatic Timoshenko beam subjected to a point force at both ends is developed based on the power series expansions. The beam is assumed to be made of linear elastic and isotropic material with constant Poisson ratio. Material properties including the ...
