"This study investigated the triaxial vibration environment in armoured vehicles to determine the characteristics of the vibration to which crewmen are exposed. Vehicles tested included the M113 Armoured Personnel Carrier, the M109 Self-propelled Howitzer, the M113½ Lynx, the Centurion Tank and the M548 Cargo Carrier, all travelling over snow-packed roads. A magnetic tape data acquisition system and a real-time method of analysis is described. The vibration spectra are compared to proposed I.S.O. vibration exposure standards to determine Fatigue and/or Decreased Proficiency Boundaries and Exposure Limits. Results indicate that the length of ride in these vehicles should be limited if the Fatigue Boundaries and Exposure Limits are not to be exceeded. Limitations of the present study are outlined and recommendations for future studies are made"--Abstract, page iii. Armored vehicles, Military Vibration Canada. Vibration Measurement.
