Dynamic Deflection of a Beam on Metal Foam
Key Engineering Materials, 2013An analytic model is developed to obtain the dynamic response of beams with initial velocities of the upper beam which is clamped at both ends and fully supported by metal foam, as a representative arrangement for protective structures. In large deflection, plastic bending and stretching in deforming regions are considered and the membrane factor ...

Large deflection dynamics and control for planar continuum robots
IEEE/ASME Transactions on Mechatronics, 2001Abstract This paper focuses on a class of robot manipulators termed “continuum” robots — robots that exhibit behavior similar to tentacles, trunks, and snakes. In previous work, we studied details of the mechanical design, kinematics, path-planning and small-deflection dynamics for continuum robots such as the Clemson “Tentacle ...

Pavement Evaluation Using Dynamic Deflections
1978Dynamic test deflections have been duplicated by elastic theory using the Chevron N-layered computer program. Dynamic surface deflections obtained using the Road Rater have been used in conjunction with elastic theory to analyze pavement behavior. A procedure has been developed to use field measured Road Rater deflections to estimate the elastic moduli

Structure Deflections and Dynamic Stringing Charts
Electrical Transmission Line and Substation Structures, 2006This paper covers structure deflections and their overall impact on transmission line system designs. Structure deflections can affect anything from simple cable blowout calculations to the complex effect on sags of conductors under unequal spans.

Dynamic analyses of traffic speed deflection devices
International Journal of Pavement Engineering, 2015AbstractTwo traffic speed deflection devices (TSDDs) that measure surface deflections at posted traffic speeds (up to 80–96 kph) were evaluated through a recent Federal Highway Administration proje...

A Distributed Sensor for Sensing Dynamic Deflections
SAE Technical Paper Series, 1998<div class="htmlview paragraph">A distributed sensor is created to sense the rate of change in deflection of beam-like structures such as crane booms. This sensor will be useful in electrohydraulic compensation of boom deflections. The sensor is made of an array of strain-sensitive segments such as strain gages or piezoelectric film.

Mathematical modelling of ice beam deflection dynamics
2021The assessment of stresses arising from the interaction of the ice field and inclined structures is an important part of research in ice mechanics. For these purposes, various mathematical tools are used, including mechanical models of beams. The article presents solutions for the equation of dynamic deflection of a beam with different boundary ...

Development of Analytical Endmill Deflection and Dynamics Models
Manufacturing, 2003Accurate knowledge of machine dynamics is required for predicting stability and precision in a machining process. Frequency response function (FRF) measurements need to be performed to identify the dynamics of the systems experimentally. This can be very time consuming considering the number of tool-tool holder combinations in a production facility. In

Deflection dynamics of rock beam caused by ultrasound
Mechanics of Time-Dependent Materials, 2013A new method for monitoring the time dependent dynamics of materials is proposed and implemented. By completely separating the conditioning (here ultrasound), the probing (here gravity), and the material state indicator (here deflection), the details of this dynamic process becomes apparent.
