Ultrasonic Wave - an overview | ScienceDirect Topics

In addition to the ultrasonic wave-driven NG, a textile fiber-based NG has been developed for harvesting low-frequency vibration/friction energies (Qin et al., 2008b).The fibers used in the fabrication were Kevlar 129 fibers, on which ZnO NWs were grown radially (Fig. 27 A).Along the entire length of the fiber, ZnO NWs exhibited a very uniform coverage and well-preserved …

warned. Within the critical range of the approach an automatic disconnection of the machine motion is activated. Means of transport only move along a tracking centre line. On the other hand the work spaces of mo-bile machines can be described by a hemisphere or a ball with excavators and concrete pumps and by a cylinder with cranes.

Working Mechanism | Scientific.Net

The tests under two kinds of commonly operating conditions for the motion of excavator were carried out by method of ultrasonic distance measuring. The results show that the motion law of working mechanism under two kinds of operating conditions was basically similar, and digging process presented periodicity clearly.

Nonlinear dynamic analysis and control of a hydraulic

Dec 03, 2018 · For an in-depth exploration of "irregular non-cyclic motion" by the three different methods, we used the maximum Lyapunov exponent and bifurcation diagrams to determine and compare non-cyclic motion. Figure 5 shows the maximum Lyapunov exponent under two different μ values. Again, because there would be a large number of graphs, we only

ultrasonics | physics | Britannica

Transducers. An ultrasonic transducer is a device used to convert some other type of energy into an ultrasonic vibration. There are several basic types, classified by the energy source and by the medium into which the waves are being generated. Mechanical devices include gas-driven, or pneumatic, transducers such as whistles as well as liquid-driven transducers such as …

A wireless sensor network will be used to detect the location of subsurface infrastructures such as a pipeline. The objective is to alert the infrastructure operator and the construction equipment operator of the threat of damage to the infrastructure. Currently the equipment operator has to depend on the color marks made by the locater sent by the One-Call center.

Fundamentals of Ultrasonic Inspection

Abstract: By analyzing the dynamic model of working mechanism for excavator, motion status of working mechanism during digging process was researched. The tests under two kinds of commonly operating conditions for the motion of excavator were carried out by method of ultrasonic distance measuring. The results show that the motion law of working mechanism …

Monitoring the Work Cycles of Earthmoving Excavators in

Monitoring the work cycles of earthmoving excavators is an important aspect of construction productivity assessment. Currently, the most advanced method for the recognition of work cycles is the "Stretching-Bending" Sequential Pattern (SBSP), which is based on fixed-carrier video monitoring (FC-SBSP). However, the application of this method presupposes the availability of …
