Abstract
A wedge three-axis inertial sensor damper suspension apparatus prevents shock and vibration impacts on a construction machine from being transferred to inertial sensors used by an automatic control system of the construction machine. The inertial sensor suspension apparatus includes a pocket, a lid, a core disposed in the pocket and covered by the lid, one or more inertial sensors attached to the core, a plurality of elastomer insertions attached to the core and forming an upper wedge between the core and the lid and a lower wedge between the core and the pocket, and a coupler that provides controlled connection of the pocket and the lid to compress the plurality of elastomer insertions using a force corresponding to a target resonance frequency for the inertial sensor suspension apparatus.
