Structural Damage Detection and Reliability Estimation using a Multidimensional Monitoring Approach

Many structural elements are exposed to load conditions that are difficult to model during the design stage, such as environmental uncertainties, random impacts and overloading amongst others, thus, increasing un programmed maintenance and reducing..

Computer-Aided Support for the Rapid Creation of Parametric Models of Milling Units for Longwall Shearers

The cutting drums are the basic working components of many mining machines. The article focuses on differencesin the design of cutting drums depending on the expected working conditions

Nonlinear regression model for ride on railway

The portable diagnosis system - SPD - evaluates the safety and ride quality aspects of the railway vehicles and the technical condition of the rail-vehicle interfac

Monitoring of condition of the railway system.

The multidimensional monitoring of symptoms applied to railway systems allow to detect and locate the sections of the track (straight and curved) that generate thedecrement of the safety and comfort of the passengers. It also evaluates the technical

Maintenance policy optimisation for multi-component systems considering degradation of components and imperfect maintenance actions

This article proposes a stochastic optimisation model in order to reduce the long-term total maintenance cost of complex systems. The proposed work is based on the following approaches: (i) optimisation of a cost model for complex multi-component systems consisting of preventive and corrective maintenance using reliability analysis, which faces two different maintenance policies (periodic block-type and age-based) and (ii) a clustering method for maintenance actions to decrease the total maintenance cost of the complex system. This work evaluates each maintenance policy and measures the effects on imperfect maintenance actions. Finally, the proposed optimisation model is applied to a numerical example which focuses on passenger urban aerial ropeway transport systems, in which the current maintenance policy has been evaluated, considering the established by the international regulation of passenger aerial cable cars. © 2018 Elsevier Lt
