A semi-automated pulse-echo ultrasonic system for inspecting tires. [Robert P Ryan; United States. National Highway Traffic Safety Administration.
Research and Development.; Transportation Systems Center.]. Semi-Automated Pulse-Echo Ultrasonic System for Inspecting Tires. Published Date: A nondestructive tire-testing system has been developed using the pulse-echo ultrasonic technique, which offers substantial advantages over all other physical nondestructive-testing methods and shows promise of reducing the cost of production-tire Author: R P Ryan.
A semi-automated pulse-echo ultrasonic system for inspecting tires. Interim : R. Ryan. Inspection Procedures and Reference Standards: In addition to evaluating the performance of the pulse-echo UT inspection method, the PoD exercise allowed for an assessment of the inspection procedures and the NDI reference necessary reference standard, shown in Fig.was deemed suitable by provides all of the appropriate flaw scenarios and transducer null points in a.
gated as indicated in table 1. A manually operated tire inspection system with photographic data recording has been fabricated utilizing the pulse-echo ultrasonic technique. Data recording equipment has been selected to furnish permanent, real time, flaw records necessary for a semi-automated inspection system.
Improved apparatus, systems, and methods for inspecting a structure are provided that use a pedestal robot mounted on a rail system, a probe extension coupler, and an inspection probe capable of performing pulse echo ultrasonic inspection.
A probe may also include sled appendages and an axial braking system to inspect over holes and off edges. For single sided inspection methods, such as pulse echo ultrasonic inspection, a single-arm robotic device, such as an RiA™ series six-axis robot from FANUC Robotics of Rochester Hills, Mich., or an IRB robot from ABB Ltd.
of Zurich, Switzerland, may be used to position and move a pulse echo ultrasonic inspection device. Apparatus, systems, and methods for inspecting a structure are provided which permit inspection of uniquely semi-automated pulse-echo ultrasonic system for inspecting tires book structures such as fuselage frames and shear ties.
Probes may be constructed from rapid prototyping. Inspection may be performed manually and may use a portable function support system for delivering fluid couplant, controlling transmit and receive functions of the inspection.
Right: data acquired with semi-automated inspection system (Pulse-echo technique, MHz) Depending on the flexibility of the part, the rigidity of the holding fixture, and the UT technique, amplitude records may reveal slight variations due to the changes in pressure applied by the inspector.
Ultrasonic methods: 3. Pulse-echo technique with analysis of A-scans in a frequency range of 50 to kHz (commercial system USD10NF, Krautkr/imer GmbH & Co.): pulse echo with probe element and separate transmitter and receiver probe at same side.
The ultrasonic pulse echo (UPE) technology extends ultrasonic pulse velocity (UPV) applications to objects where access is restricted to a single side. Proceq Pundit offers the most versatile range of ultrasonic testing instruments that are ergonomic and portable.

Before testing the. This paper proposes an ultrasonic testing system for inspection of pitting corrosion cracks in rivets of multilayer structures.
When an ultrasonic angle-beam pulse-echo setup is used, two. To illustrate the general inspection principle, a typical pulse/echo inspection configuration as illustrated below will be used. A typical UT inspection system consists of several functional units, such as the pulser/receiver, transducer, and display devices.
A pulser/receiver is an electronic device that can produce high voltage electrical pulses. This article considers the two primary methods used for ultrasonic inspection: pulse-echo and the transmission methods. Pulse-echo inspection can be accomplished with longitudinal, shear, surface (Rayleigh), or Lamb (plate) waves using a diverse range of transducers.
The article discusses the principles of each of these inspection methods. Pulse Echo. In pulse-echo testing a transducer sends out a pulse of energy and the same, or a second transducer listens for reflected energy. Pulse echo is especially effective when only one side of a part is accessible.
Phased Array Pulse Echo. The main advantages offered by phased array are increased sensitivity, coverage and speed.

1 Introduction. This practice 2 covers straight and angle beam contact, pulse-echo ultrasonic examination of austenitic steel forgings produced in accordance with Practice A/AM and Specifications A/AM and A/AM.
Ultrasonic examination of nonmagnetic retaining ring forgings should be made to Practice A/AM rather than this practice. Automated ultrasonic testing reduces the ultrasonic inspection time for many different applications. Corrosionpedia explains Automated Ultrasonic Testing (AUT) Automated ultrasonic testing uses the same basic components as regular ultrasonic testing, including pulsers, receivers, transducers, computers and display equipment, although a.
Although not all requirements of this practice can be applied universally to all inspection situations and materials, it does provide the basis for establishing contractual criteria between suppliers and purchasers of materials for performing contact longitudinal wave pulse-echo examination and may be used as a guide for writing detailed procedures for particular applications.

UEDA and H. MURATA Echo patterns obtained by using an ultrasonic pulse-echo system are mainly determined by the structure of an object, but are influenced by many other factors such as the directivity and damping characteristics of the ultrasonic transducer, the dynamic range of the display unit and so on.
Ultrasonic Testing – Pulse-Echo Method. The method is based on mechanical waves (ultrasound) generated by a piezo-magnetically excited element at a frequency typically in the range between 2 and 5 MHz.
Control involves the transmission, reflection, absorption of ultrasonic propagated wave in the controlled part. Transmitted wave beam is.

Ultrasonic Pulse Echo technique namely Contact and Immersion testing for inspecting typical hem bonded automotive joints. The joints have been tested for disbond at the various metal-adhesive interfaces by using an ultrasonic scan comparison method which compares the acquired signals against a reference scan from the unbonded metal sheet.
Improved apparatus, systems, and methods for inspecting a structure are provided that use a pedestal robot mounted on a rail system, a probe extension coupler, and an inspection probe capable of performing pulse echo ultrasonic inspection. A probe may also include sled appendages and an axial braking system to inspect over holes and off edges.
General questions about ultrasonic testing. 1. What is it? Ultrasonic nondestructive testing, also known as ultrasonic NDT or simply UT, is a method of characterizing the thickne. Some of the problems occuring when pulse-echo ultrasonic inspection of defects in anisotropic homogenouus media is carried out are considered in this.
The process of pulse echo ultrasound techniques involve the transmission of ultrasound pulses into the metal subsection being examined. Echo signals resulting from the contact are bounced, reflected or otherwise scattered from the metal's surface in response.
