Abstract
The report reviews two procedures for evaluating the vibration ride-quality of vehicles. The first is based on the current International Standard (ISO 2631). The second is a procedure for evaluating impulse vibration. It is based on Payne's model for determining the peak spring strain in the human spine and on Allen's proposed specification for human tolerance to repeated shocks. An electronic analogue of Payne's model was developed to produce values of the Dynamic Response Index (DRI) from successive peaks in the acceleration-time history of a z-axis vibration signal, and Allen's comfort and injury criteria when applied to the accumulated DRI exposure. Three Canadian Forces vehicles were studied: (1) M113 APC driven at 20 kph across country; (2) five-quarter ton truck at 50 kph, rough pavement; and (3) Centurion Tank at 12 kph, cross country.
