The reconfigurable vibrating screen (RVS) machine is an innovative beneficiation machine designed for screening different mineral particles of varying sizes and volumes required by the customers’ through the geometric transformation of its screen structure. The successful RVS machine upkeep requires its continuous, availability, reliability and maintainability. The RVS machine downtime, which c...

This paper gives a practical systematic approach towards the maintenance procedure optimisation of critical industrial unit in operation, to improve its maintainability. The resolution maintainability challenge (Vibrating screen - VSU) was realised by performing two-phase analysis, encompassing criticality and assessment. assessment comprised failure investigation using fault tree analysis (FTA...

Multiple frequencies constraints and analytical sensitivity methods were used in structural optimization design of the side plate of 4YK1860 vibrating screen to lower the damage of side plate caused by high dynamic stress. The mass of side plate of the vibrating screen was taken as object function, mode frequencies were regarded as state parameters, size of plate were used as constraint paramet...

The reliability level for a nuclear installation is given in generally by the technological process quality of operation and maintenance and in particular by a lot of technical, technological, economic and human factors. The maintenance role is fundamental for a nuclear installation. In the maintenance activity as in any dynamic area, appear continuously new elements which, sometimes, require n...

Earth pressure balance tunnel boring machines (EPB-TBMs) are favorably applied in urban tunneling projects. Despite their numerous advantages, considerable delays and high maintenance cost are the main disadvantages these machines suffer from. Reliability, availability, and maintainability (RAM) analysis is a practical technique that uses failure and repair dataset obtained over a reasonable ti...

Holonic control is generally used in reconfigurable manufacturing systems since the modularity of holonic control holds the promise of easier reconfiguration, reduction in complexity and cost, along with increased maintainability and reliability. As an alternative to the commonly used agent-based approach, this paper presents an Erlang-based holon internal architecture and implementation method...

Good maintainability is an essential feature for machines and processes in industry. It promotes, among others, maintenance safety, postmaintenance reliability and cost-effective maintenance by ensuring quick and easy operation and short downtime. Virtual engineering tools provide an effective way for maintainability design already during the design phase. Machine designers may not consider mai...

Article history: Received 28 October 2011 Accepted December, 5 2011 Available online 8 December 2011 Continuous generation of electricity of a power plant depends on the higher availability of its components/equipments. Higher availability of the components/equipments is inherently associated with their higher reliability and maintainability. This paper investigates the reliability, availabilit...
