Further Development of Wear Calculation and Wear Reduction in Cold Forging Processes [PDF]

open access: yesJournal of Manufacturing and Materials Processing, 2021
Tools are of strategic importance for industrial manufacturing processes. Their behaviour has a great influence on the productivity of the process and the quality of the product.

Recent Progress on Wear‐Resistant Materials: Designs, Properties, and Applications

open access: yesAdvanced Science, 2021
There has been tremendous interest in the development of different innovative wear‐resistant materials, which can help to reduce energy losses resulted from friction and wear by ≈40% over the next 10–15 years.

Use of a targeted, computer/web-based guided self-help psychoeducation toolkit for distressing hallucinations (MUSE) in people with an at-risk mental state for psychosis: protocol for a randomised controlled feasibility trial

open access: yesBMJ Open, 2023
Introduction Individuals who access at-risk mental state (ARMS) services often have unusual sensory experiences and levels of distress that lead them to seek help.

A study on the countermeasure method for gauge corner cracking by applying the worn profiles of rail

open access: yesNihon Kikai Gakkai ronbunshu, 2022
In Japanese railway networks, the gauge corner cracking (GCC) occurs to the head hardened rail of the high rail in curved sections of R600 to R800m. In case of the GCC propagates deeply, it will be a possibility of causes rail broken.

Proposal of the rail profile selection method to reduce gauge corner cracking initiation by mitigating contact conditions of wheel and rail

open access: yesNihon Kikai Gakkai ronbunshu, 2022
The gauge corner cracking (GCC) occurs on heat treated rails of the high rail in curved sections with a radius of 600 to 800m. In case of GCC propagates deeply, it may cause rail breakage.

Managing Unusual Sensory Experiences in People with First-Episode Psychosis (MUSE FEP): a study protocol for a single-blind parallel-group randomised controlled feasibility trial

open access: yesBMJ Open, 2022
Introduction Hallucinations (hearing or seeing things that others do not) are a common feature of psychosis, causing significant distress and disability. Existing treatments such as cognitive–behavioural therapy for psychosis (CBTp) have modest benefits,

Development of a model for predicting worn profile of rail under the mixed slip conditions

open access: yesNihon Kikai Gakkai ronbunshu, 2020
Rail wear does not develop in a short term, but it is closely related to crack initiation. Furthermore, there is a possibility that the worn profile of rail influences the curving performance or the running stability.

Numerical study of railway wheel wear on roller rigs

open access: yesNihon Kikai Gakkai ronbunshu, 2020
The dynamic behavior of railway vehicle is often tested by roller rig equipment and this test is very useful. However, it is known that contact condition on roller rig is different from the case that wheels run on rail.

A study on the modelling for predicting worn profile of rail with multi-body dynamics and the verifying the validity

open access: yesNihon Kikai Gakkai ronbunshu, 2017
In recent years, railway system is attracting attention in terms of energy efficiency and environment friendliness. Rail of railway is one of the most important elements in constructing railway system.
