Continuous friction measuring equipment
Web1 day ago · Here, wire-based friction stir additive manufacturing (W-FSAM) was proposed, which can realize the solid-state manufacturing of large metallic structures via continuous feeding of wire materials. The main W-FSAM tools include a storage chamber with a wire feeding port, a screwed transport structure, and three stirring probes.

WebContinuous use and / or weather can cause doubt to exist over the Runway surface braking conditions. To ensure the safe operation of Aircraft, the condition of the Runway needs to be evaluated regularly and reported as appropriate in order to reduce Risk to Life. Contents 3272(1): Continuous Friction Measuring Equipment WebThe CFME in question are those which use a torque measuring sensor to determine friction readings. In these devices, the torque exerted on the testing tire by deeper contaminants opposes the torque exerted by the pavement, resulting in a very low, overly conservative reading.
