Dynamic ultrasonic inspection technology for chinese EMU and application in China
نویسندگان
چکیده
wheel-set is an important part of EMU. It directly influences the EMU operation security. In recent years, some harmful circumferential and radial defects are found in the wheel rim, which occur between the periods of two light maintenances. The comprehensive security system of wheel-set has already built in china to guarantee the EMU maintenance quality and operation security. It consists of regular mobile inspection, regular stationary inspection and daily dynamic inspection. An ultrasonic testing technology for EMU wheel-set dynamic inspection and successful application in china is described in this paper.

As an international legal instrument, the International Health Regulations (IHR) is internationally binding in 196 countries, especially in all the member states of the World Health Organization (WHO). The IHR aims to prevent, protect against, control, and respond to the international spread of disease and aims to cut out unnecessary interruptions to traffic and trade. To meet IHR requirements,...
متن کاملA Novel Method for Ultrasonic Evaluation of Horizontal Defects Using Time-of-Flight Diffraction
Time-of-flight diffraction method (ToFD) is an amplitude-independent sizing method which is based on the measurement of time-of-flight of defect tip diffracted waves. Although ToFD can measure through-wall length of defect accurately, this method is not capable of measuring horizontal defect size. In this paper, a new ToFD method for evaluating horizontal planar defects is presented. The finite...

Background: The dynamic phantom is one of the best tools to study the impact of motion on tumor target delineation and absorbed dose verification during dose delivery. Materials and Methods: this study, a 6-DOF (degrees of freedom) phantom was designed following the stacked serial kinematics and assembled by six commercial motion stages to generate 6-DOF motion, which were RotX (pitch, around X...
متن کاملRefnement of Cane Molasses with Membrane Technology for Clarifcation and Color Removal
Recovery of sugars from cane molasses (i.e. the by-product of sugar industries) is of great interest to industry and academia. The prerequisite for refning cane molasses is removal of pigments and suspended solids present in the molasses. In this work, the utilization of membrane separation for clarifcation and decoloration of cane molasses has been examined. Three oper...
