Abstract Pyramidal truss sandwich panels (PTSPs) are widely used in engineering structures and their face sheets core parts generally bonded by the welding process. A large number of solid elements usually required finite element (FE) model a PTSP with welded joints to obtain its accurate modal parameters. Ignoring can save many degrees freedom (DOFs), but significantly change natural frequencies. This study aims accurately determine parameters much fewer DOFs than those operational analysis...
Two-dimensional Green's functions for a line heat source applied in the fluid and pyroelectric two-phase plane are presented this paper. By virtue of two-dimensional general solutions which expressed harmonic functions, six newly introduced with undetermined constants constructed. Then, all components can be derived by substituting these into corresponding solutions. And obtained interface compatibility conditions mechanical, electric, thermal equilibrium conditions. Numerical results given...
Fatigue failures at fastener holes in structures are undesirable as they can lead to catastrophic mechanical failures. Interference pins create interference fits with joined components reduce stresses around and extend the fatigue life of a structure. In this research, novel method for finite element (FE) modeling pin connections wind turbine lattice tower component was developed. The installation modeled using two-stage process that causes local stiffness changes members component. were...
Developing a miniatured laser vibrometer becomes important for many engineering areas, such as experimental and operational modal analyses, model validation, structural health monitoring. Due to its compact size light weight, can be attached various mobilized platforms, an unmanned aerial vehicle robotic arm whose payloads usually not large, achieve flexible vibration measurement capability. However, integrating optics into miniaturized presents several challenges. These include signal...
ABSTRACT Fiber optic current sensors have made unprecedented contributions to the safety and security of power grids. The λ/4 retarder, as a key component for generating circular polarization, can significantly enhance performance fiber (FOCS) due its superior characteristics. However, traditional methods fabricating homemade retarders inherent flaws. This study replaced retarder in all‐fiber sensor with an integrated which is proposed convert linearly polarized light into circularly by...
Because most piezoelectric devices have interfaces with fluid in engineering, it is valuable to study the coupled field between and media. As fundamental problem, 3D Green’s functions for point forces charge loaded bimaterials are studied this paper. Based on general solutions expressed by harmonic functions, we constructed suitable undetermined constants at first. Then, couple can be derived substitution of into solutions. These obtained virtue compatibility, boundary, equilibrium...
Abstract This study proposes a novel general-purpose 3D continuously scanning laser Doppler vibrometer (CSLDV) system to measure full-field vibration of structure with curved surface in non-contact and fast way. The proposed CSLDV consists three CSLDVs, profile scanner, an external controller, is experimentally validated by measuring turbine blade under sinusoidal excitation identifying its operating deflection shapes (ODSs). A zig-zag scan path for the based on results from 6scan angles...
In this work, we study the pandemic course in United States by considering national and state levels data. We propose compare multiple time-series prediction techniques which incorporate auxiliary variables. One type of approach is based on spatio-temporal graph neural networks forecast utilizing a hybrid deep learning architecture human mobility Nodes represent state-level deaths due to COVID-19, edges trend temporal correspond node attributes across time. The second statistical technique...
