DSM Vertical Linear Accelerator for Vestibular Testing - Horizontal Air Bearing Test

Horizontal Air Bearing Test Prior to Carriage Install and Beam Stand Up

PROJECT:
Main Goal: To provide vertical linear oscillation stimuli to the otolith organs, which are apparently less well understood than the semicircular canals.
Motion Quality: Device must be as smooth and as quiet as possible to provide isolated stimulus to the saccule. This is accomplished in part by the use of brushless linear motors and air bearings as the primary mover and guidance components.
Motion Requirements: 12ft. stroke, 2Hz freq. response, 1G peak acceleration, 182kg total payload, ± 3mm position error, arbitrary waveform capability.
DVA Test: The VLA will include an integrated dynamic visual acuity (DVA) tester.
Safety System: To ensure that an uncontrolled fall does not occur, a triple redundant safety scheme utilizing long travel impact bumpers, rail brakes, and dynamic braking is being implemented.
Completion: DSM plans to have the VLA completed Spring 2011
