TM 260.04 Frictional Vibrations Didactic Equipment Vocational Training Equipment Mechanical Training Equipment
Differences between static and sliding friction, instability Features - slip–stick phenomenon at the transition from static to dynamic friction - friction rings of different materials for the study of different friction pairings Learning objectives/experiments - together with the drive unit -- observation of the transition from static to dynamic friction -- influence of lubrication on slip–stick phenomenon -- influence of the force between the friction partners on the slip–stick phenomenon -- influence of the relative velocity of the friction partners on the slip–stick phenomenon Specification [1] friction oscillations at static and dynamic friction [2] quick and easy assembly of the experimental unit on the frame of the drive unit [3] rotating stainless steel disk [4] disk is driven by a clampable coupling between drive unit and gear unit [5] friction ring of different materials: stainless steel, brass or plastic (PA) [6] friction pair subject to load by stepped weights [7] frictional force measured by force sensor [8] displays of force and speed and speed adjustment on the drive unit Technical data Disk - Ø: 60mm - stainless steel Friction ring - outer diameter: 80mm - inner diameter: 50mm - 1x stainless steel - 1x brass - 1x plastic (PA) Force sensor for frictional force - 0...50N Weights - 1x 5N - 3x 10N Weight: approx. 7kg
