Analytical Investigation of Dynamic Response in Cracked Structure Subjected to Moving Load

Buildings
Under cyclic moving load action, tensile-dominant structures are prone to crack initiation due to cumulative damage effects. The presence of cracks leads to structural stiffness degradation and nonlinear redistribution of dynamic characteristics, thereby

Dynamic Modeling of Motor Deep Groove Ball Bearing Skidding and Simulation Study of Temperature Field Characteristics

World Electric Vehicle Journal
High-speed traction motors in electric vehicles (EVs) subject their support bearings to severe mechanical and thermal loads. Bearing skidding and frictional heat generation can cause abnormal temperature rises, whereas uncertainty in convective heat ...

Moving load on elastic structures: passage through the wave speed barriers [PDF]

The asymptotic behaviour of an elastically supported infinite string and an elastic isotropic half plane (in frames of specific asymptotic model) under a moving point load are studied. The main results of this work are uniform asymptotic formulae and the

Ghost imaging of a moving target with an unknown constant speed

, 2014
We report a method for ghost imaging of a moving target with an unknown constant speed. By both numerical simulations and experiments, it is shown that by matching the calculated signal to the recorded data, the unknown speed can be correctly retrieved ...

Intelligent Troubleshooting of Vertical Bandsaws, Leveraging Ensemble Learning on Low-Level Data

IEEE Access
Bandsaw machines are the backbone of the modern wood industry. Due to immense load stresses and operational speeds various parts may fail frequently, hence constant monitoring is required. Most of the time small faults like imbalance or sturdiness, which

Dynamical response of a prestrained system comprising a substrate and bond and covering layers to a moving load

, 2009
The dynamical response of a system consisting of a prestressed substrate and covering and bond layers to a moving load is investigated within the scope of a piecewise-homogeneous body model by using a three-dimensional linearized theory of wave ...

Dynamic response of an annular disk to a moving concentrated, in-plane edge load

, 1980
In-plane dynamic behaviour of a thin annular disk with a clamped inner boundary is analyzed. The frequencies of free in-plane vibration with a free outer boundary are first evaluated, by using Lamé potentials, for various radius ratios ranging from 0.2 ...

Moving Loads on an Elastic Plate Strip

, 1974
The response of an infinite plate strip under an arbitrarily distributed transverse moving line load is determined. The line of application of the load is perpendicular to the infinite edges, and the load is assumed to propagate parallel to the infinite ...
