Nanoclay has proven to be an active anti-corrosive additive due the self-repairing effect from nanoclay swelling and expansion, except for its passive barrier high aspect ratio. But it is still uncertain how these effects of are intertwined with other components in a complex coating system corrosive environments. In this study, we examined combined nanoclays two particle sizes commonly used cos...

Abstract Sliding and spinning behaviors significantly affect the performance of rolling bearings, especially for dry-lubricated micro macro sliding may lead to increased wear solid lubricating film. A unified contact tribology analytical model is proposed angular ball bearings (ACBBs) considering extreme conditions including high combined loads effects. comprehensive solution framework ensure r...

In the last ten years we have seen fast development in the computational methods used in all fields of engineering. The possibility of getting rapid and accurate models of High Voltage (H.V.) Switchgear can reduce considerably the high cost of development testing. In this paper the Boundary Element Method (BEM) is discussed from an industrial user point of view. First we analyse the advantages ...

Curve squeal is a highly disturbing tonal sound generated by rail vehicles like trains, metros or trams, when negotiating sharp curve. The probability that occurs increases with reduced curve radius of the track. noise attributed to self-excited vibrations caused stick/slip behaviour due lateral creepage wheel tyre on top rail. With respect large number rolling stock units and long lifetime veh...
