  • Topics in Modal Analysis II, Volume 8
    Each mass carriage suspension has anti-friction ball bearing systems and, therefore, the linear dashpots are included only to describe small viscous dampings. Each mass carriage has a ( rotary ) high resolution optical encoder to measure its actual positions via cable-pulley systems (with effective resolutions of 2,266 pulses/cm or 4.413 10 3 mm /pulse).
  • Actuators For A Segmented Mirror Control System
    2.3 Integral Bearing Roller Screw The heart of the actuator is the integral bearing roller screw. It provides a smooth, low friction, high load capacity mechanism for converting rotary to linear motion with 3 mm dynamic range yet resolution at the 4 nanometer level.
  • Rolling Friction in a Micro Tribosystem
    The viscoelastic model was applied to the rolling contacts from the linear microball system used in [1 … Ghalichechian et al. [ 3 ] experimentally determined the friction coefficient in an encapsulated rotary microball bearing mechanism using microfabricated silicon and stainless steel microballs of 0.285- mm diameter.
