Wear Based Lifetime Estimation of a Clutch Facing using Coupled Field Analysis

International Journal of Automotive and Mechanical Engineering, 2021
Repetitive use of the clutch, over a period of time, causes the friction material at the contact surfaces (clutch facing and flywheel/pressure plate) to wear, thus deteriorating its performance and usable life. The working life of a rigid clutch is the limiting factor when it comes to extracting maximum performance from a dual mass flywheel system ...

Face dog clutch engagement at low mismatch speed

Periodica Polytechnica Transportation Engineering, 2010
Face dog clutches regain popularity in heavy duty AMT´s. Though the reduction of the speed difference between the dogs is the key to a smooth gear shift, the excellent engaging capability is experienced to degrade at low mismatch speed and the outcome of the engagement process becomes uncertain.

1: MERRIAM'S WILD TURKEY IN THE BLACK HILLS OF SOUTH DAKOTA*

Wildlife Society Bulletin, 1973
Eight wild‐trapped Merriam's turkeys (Meleagris gallopavo merriami) were introduced into the Black Hills of South Dakota in March 1948. Two booster plantings of wild‐trapped birds, one of 15 in 1950 and one of 6 in 1951, completed the introduction ...

Scoring Control of Asbestos-Free Glass-Fiber Clutch Facing.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1993
Recent manual transmissions are equipped with asbestos-free clutch facing. The authors have been developing organic-type facing materials for the past 10 years. Rubber with glass-fiber composite material has the features of long life, high-temperature durability, and mild friction characteristics in low-speed sliding contact, but is aggressive to the ...

Ecological portraits: Mapping functional spectra and space characteristics of birds in China

Global Ecology and Conservation
The functions of wildlife species in ecosystems and their responses to environmental changes are mediated through their functional traits. By mapping the gradient across the diversity of bird ecological strategies (functional spectra) and quantifying the

Investigation of effective conservation measures for the critically endangered White-bellied Heron Ardea insignis using an integrated population model and Bayesian population viability analysis

Avian Conservation and Ecology
Although conservation efforts worldwide have transitioned toward landscape and regional approaches, species such as the White-bellied Heron Ardea insignis still require targeted actions because of their extremely small and declining population size and

Breeding ecology of the common myna Acridotheres tristis: rural nestlings exhibit enhanced growth compared to urban conspecifics

Journal of Avian Biology
Urbanization alters ecological conditions, yet its impacts on avian reproduction are not fully understood. In many bird species, nestlings growing up in cities tend to have slower growth rates and poorer body conditions than those in rural areas.
