Building structures are very often operated under the action of dynamic loads, both natural and man-made. The calculation influence static loads has been quite widely studied in detail. When exposed to additional tests carried out, where measuring instruments installed on register stresses deformations that occur during influences. Elastic elements responsible functional unit many instruments. ...

The mixture unified gradient theory of elasticity is invoked for the rigorous analysis dynamic characteristics elastic nanobeams. A consistent variational framework established and boundary-value problem equilibrium enriched with proper form extra non-standard boundary conditions detected. As a well-established privilege stationary theorems, constitutive laws resultant fields cast as differenti...

Aiming at the structural reliability and operation stability of vibrating screen, this study takes 2460 double-layer circular screen as research object, applies Creo to build a three-dimensional model uses ANSYS Workbench analyze dynamic characteristics screen. Through modal analysis, natural frequencies vibration modes are obtained. harmonic response displacement stress distribution its workin...
