Machine Vision Condition Monitoring of Heavy-Axle Load Railcar Structural Underframe Components

Economics of Pavement Condition , Axle load , and Vehicle Operating Costs

T total cost of moving goods by truck over a highway system involves two basic compon~nts: -the public costs associated with construction and maintenance of the road network, and the privately financed costs of acquiring, operating, and maintaining a fleet of trucks. These publicly and privately financed costs are directly linked in many ways. For instance, the more trucks there are, the more w...

Real-time on-board condition monitoring of train axle bearings

Premature failure of rail axle bearings causes a significant increase in train operating costs and can impact train safety. A new on-board condition monitoring approach provided by Perpetuum Ltd is fitted on passenger trains to provide the operator with real-time information on bearing health. This new technology allows the detection of early bearing damage. This paper reports an initial study ...

Condition Monitoring of Micro-drilling Processes on Glass by Using Machine Vision

Optical and medical devices require microdrilling of holes on glass. Brittle fracture occurs during the drilling. Cone and radial cracks are generated due to impact load and walking when a drill hit a glass to make a hole. To produce good holes without cracks and fracture, a condition monitoring of glass drilling processes is required. In this paper, to develop a costeffective direct monitoring...

Machine-Condition Monitoring using Vibration Analysis

Sensor Fusion for Machine Condition Monitoring

Machinery maintenance accounts for a large proportion of plant operating costs. Compared with the conventional scheduled maintenance strategy which is to stop the machine at pre-determined intervals, modern condition-based maintenance strategy stops the machine only before there is evidence of impending failure. With the development of cheaper sensors, more and more sensors are designed for mac...
