Motion Base Simulation Test of an M9 Armored Combat Earthmover (ACE) Driver's Hatch.

摘要

This report details the System Simulation Technology Division's effort in conducting a motion base simulation test of the M9 Armored Combat Earthmover (ACE) driver's hatch. The hatch was mounted to a three axis motion simulator capable of producing vertical, pitch, and roll dynamics to the hatch. Hydraulic actuators are commanded and controlled by a servo control system and a Computer Automated Measurement and control (CAMAC IEEE-583). The time history dynamics of the hatch were predetermined by a computer model of the dynamics of the M9 ACE. A short analysis of some field data from the M9 ACE is detailed. It suggests an amplitude level and frequency range to perform a vibration test which was conducted.
