Nov 25, 2020 · A fracture screening method is needed that will help doctors, schoolteachers and others more reliably decide which children should have an xray. Vibration is reliably used in industry to find defects such as cracks in machines and other structures. The researchers believe that vibration can similarly find fractures in bones in children.

· Sinusoidal vibration tests typically are not as helpful as random testing in certain condition since a sine test focuses on single frequency consistently. A random vibration test, however, always excites all the frequencies within a defined spectrum. Wayne Tustin's had a good lay person's description of random vibration:

Apr 11, 2019 · The dynamic response of the vibrating screen has a great impact on the screening efficiency and fatigue life of the structures. For the conventional dynamic design, the consideration of the influence of load weight on dynamic response is lacking. So, in this paper, taking a very common vibrating screen used in tunnel construction as an example, the relationship between the screen .
