... on friction. A prototype was built from wood and plastics. This was evaluated in a CT-scanner for accuracy and reliability with four subjects. A usability test was performed with 20 radiology technicians who were asked to perform four tasks with the prototype and fill out a questionnaire. The prototype can...

... frequency friction simulator has been used for the experiment where specimens were manufactured with 50 mm diameters and 50 μ m clearance. A dynamic loading was applied synchronized with Hip CD 98 while the temperature was controlled at 37 ° C . The output data including friction coefficient, friction force...

..., showing that the axial friction force is reduced, with a factor of 6.4, from 1.4 N to 0.22 N. cardiovascular device human performance/force assessment medical device design process minimally invasive devices Measurement setup, where the sheath is clamped on two places and the catheter tip...

... to the eye and has three degrees of freedom. The eye is free to rotate under the applied moment. The applied moment and the resulting angle are measured to calculate the rotational stiffness of the eye. Parasitic forces are minimized by keeping friction, inertia and stiffness in the mechanism to a minimum...

... factor on one of the two terms in the model was necessary to achieve best results, but proved to be accurate for all 100 + tests completed. With it, this model accounted for the following parameters: Angular displacement of tube bends, radial clearance, coefficient of friction, lengths, tube and filament...
