Forces in the Main Bearings of Multicylinder Engines

SAE Technical Paper Series, 1966
<div class="htmlview paragraph">The conventional methods of computing the main-bearing forces result only in a rough approximation of the actual bearing loads. The reasons for the deviations between measured and calculated loads are investigated.

Probabilistic Main Bearing Performance for an Internal Combustion Engine

Journal of Tribology, 2004
Abstract A probabilistic analysis is presented for studying the variation effects on the main bearing performance of an I.C. engine system, under structural dynamic conditions. For computational efficiency, the probabilistic analysis is based on surrogate models (metamodels), which are developed using the kriging method.

The evolution of the science of Bear Brook Watershed in Maine, USA

Environmental Monitoring and Assessment, 2010
The Bear Brook Watershed in Maine (BBWM), USA is a paired watershed study with chemical manipulation of one watershed (West Bear = WB) while the other watershed (East Bear = EB) serves as a reference. Characterization of hydrology and chemical fluxes occurred in 1987-1989 and demonstrated the similarity of the ca.

Failure Analysis of a Helicopter's Main Rotor Bearing

Key Engineering Materials, 2012
Presented results report some of the findings of a detailed failure analysis carried out on a main rotor hub assembly, which had symptoms of burning and mechanical damage. The analysis suggests environmental degradation of the grease which causes pitting on bearing-balls.

The Bear Brook Watershed, Maine (BBWM), USA

Environmental Monitoring and Assessment, 1999
The Bear Brook Watershed Manipulation project in Maine is a paired calibrated watershed study funded by the U. S. EPA. The research program is evaluating whole ecosystem response to elevated inputs of acidifying chemicals. The project consists of a 2.5 year calibration period (1987–1989), nine years of chemical additions of (NH4)2SO4 (15N- and 34S ...
