Study on the Time-Varying Stiffness Characteristics of Four-Point Contact Ball Bearings

open access: yesLubricants
This paper takes a four-point contact ball bearing of a wind turbine as the research object, analyzes the force and deformation relationship under the combined action of axial load and radial load, obtains the load distribution of rolling elements, and ...

Wyboczenie Pręta Pryzmatycznego jako Zagadnienie Dynamicznej Teorii Plastyczności

open access: yesEngineering Transactions, 1956
The buckling of a prismatic bar in the plastic region (strictly speaking its breakdown under axial forces) was investigated experimentally among others by M. Broszko who presented his results in Ref. [2]:  These results led Broszko to the conclusion that

Application of Pattern Search Method to Power System Economic Load Dispatch

open access: yes, 2007
Direct Search (DS) methods are evolutionary algorithms used to solve constrained optimization problems. DS methods do not require information about the gradient of the objective function while searching for an optimum solution.

Fatigue load optimization and test verification of the full-scale aileron

open access: yesJixie qiangdu
In the fatigue test of aircraft wing structural components, the fatigue design loads need to be optimized so as to reduce the bending, shear and torsion load errors applied during the test.

Influence of loading pattern in four-point bending tests

open access: yes, 1998
This paper presents the results of a study where the fatigue life of a dense bituminous mixture was evaluated for three different types of loading pattern. The first loading pattern was a sinusoidal wave, the second was a haversine wave and the third was a modified sinusoidal wave. The rest period was 50% of the load time.
