Fretting test rig with variable normal force

Test Rig for Friction Force Measurements in Pneumatic Components and Seals

This article describes the design of a new test rig for measuring the friction force in pneumatic components and seals. The test rig was designed in order to measure both the overall friction force in a pneumatic cylinder or a valve as a whole, and the single contribution to friction force caused by the sliding seals. To this end, special fixtures and devices were designed and manufactured in o...

Preliminary results on multi-body dynamic simulation of a new test rig for wheel-rail contact

The ability to perform rolling contact fatigue (RCF) experiments in wheel–rail material is provided by a new small–scale test rig, manifesting the actual dynamic behaviour of the railway system. In this paper, a multi-body dynamics (MBD) model is proposed, simulating the vibration behaviour of the prescribed rig. The new testing facility is modelled using a three-dimensional model of the vehicl...

Development of a Test-rig for a Modern Motorcycle Engine

This paper presents experimental activities that have been performed in the Automotive Engineering Centre laboratories in Universiti Malaysia Pahang for developing a test-rig based on a modern motorcycle engine. The experimental engine test-rig was developed based on an eddy current dynamometer which was coupled to a four-stroke singlecylinder SI motorcycle engine. Moreover, the test-rig consis...

Variable Normal sleep Shallow

Figure 1. Breakdown of the memory performance for the declarative and implicit tasks. left panel: Subjects having undergone sleep manipulation show a significantly reduced number of true positive responses and an increase in the false negative responses (forgotten items). The absence of differences in the true negative and false positive categories indicates that the memory performance after sh...
