The transverse vibration frequency of conveyor belts is an important parameter describing the dynamic characteristics a belt conveyor. This most often identified from theoretical relationships, which are derived on basis assumption that stationary elastic string. Belt vibrations have number analogies to other tension member systems, such as, for example, power transmission belts. Some research ...

The classical shell theory, first-order shear deformation theory, and third-order shear deformation theory are employed to study the natural frequencies of functionally graded cylindrical shells. The governing equations of motion describing the vibration behavior of functionally graded cylindrical shells are derived by Hamilton’s principle. Resulting equations are solved using the Navier-type s...

Fiber optic sensors are often used as acoustic to detect sound waves because of their apparent advantages, such anti-electromagnetic interference and strong adaptation the environment. The transverse vibration mode fiber caused by wave can be obtained, principle optical sensor signal was explored using a simple model. It is found that effectively cause change in birefringence only when number a...

The aim of this paper is to conduct experimental modal analysis and numerical simulation to verify the structural characteristics of a deployable-retractable wing for aircraft and spacecraft. A modal impact test was conducted in order to determine the free vibration characteristics. Natural frequencies and vibration mode shapes were obtained via measurement in LMS Test. Lab. The frequency respo...

Transmission lines are affected by the natural environment for a long time, and bolts prone to frequent vibration, resulting in loosening or falling off. In this paper, loose mechanism of transmission line threaded connection is analysed, transverse vibration comparative test bolt locking method carried out. A new type nut has been developed, which good performance convenient installation. Acco...

Although vocal folds are known to be anisotropic, the influence of material anisotropy on vocal fold vibration remains largely unknown. Using a linear stability analysis, phonation onset characteristics were investigated in a three-dimensional anisotropic vocal fold model. The results showed that isotropic models had a tendency to vibrate in a swing-like motion, with vibration primarily along t...
