Design oriented simulation of contact-friction instabilities in application to realistic brake assemblies [PDF]

, 2010
This paper presents advances in non-linear simulations for systems with contact-friction, with an application to brake squeal. A method is proposed to orient component structural modifications from brake assembly simulations in the frequency and time ...

Triboelectric–Electromagnetic Generator‐Enabled Hybrid Power Backpack for Self‐Powered Field Safety Management

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A lightweight hybrid backpack integrating SC‐TENGs and R‐EMGs harvests biomechanical energy during walking. With a low activation speed of 3 km h−1 and a high specific power of 0.18 W kg−1, it enables self‐powered field safety management. The power backpack refers to an energy‐harvesting solution engineered to mitigate battery reliance in wearable ...

Assessment of the effects of microwave‐produced biodiesel blends on electric generator performance and emissions

Environmental Progress &Sustainable Energy, EarlyView.
Abstract Biodiesels are emerging as alternatives to diesel fuel. However, to be a feasible solution, biodiesels must meet strict criteria including high efficiency and minimal environmental impact. The current study focuses on evaluating ethyl ester biodiesel and its blends with diesel fuel to assess their potential.

Analysis of wear in organic and sintered friction materials used in small wind energy converters

Materials Research, 2008
Wind energy converters of small size used in isolated units to generate electrical energy must present low maintenance cost to such facilities economically viable. The aspect to be analyzed in cost reduction is the brake system, since in isolated systems

Defining sagittal knee phenotypes via monopedal static anterior tibial translation. Part 1: Translating weight‐bearing sagittal position into clinical risk profiles

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Static anterior tibial translation (sATT) is a reproducible monopodal weight‐bearing radiographic parameter that reflects the resting sagittal position of the tibiofemoral joint. Distinct from manual laxity tests that quantify passive displacement limits, sATT captures the functional equilibrium of the tibia under physiological load ...

Wear of brake blocks for in-service conditions-Influence of the level of modelling

, 2014
Wear of brake blocks at tread braking of railway wheels is one of the key factors that control the time period between scheduled train maintenance and hence has a substantial impact on the life cycle cost of the vehicle.
