Abstract
An extensive field testing of an in-service M113A1 APC was carried out at Land Engineering Test Establishment (LETE), Ottawa, for various vehicle configurations, speeds, and field courses. Prior to field testing, a test plan indicating appropriate instrumentation/equipment, their locations and mounting methods, and a detailed outline of test runs in view of vehicle configuration, terrain profile, vehicle speeds, was prepared by CONCAVE in collaboration with LETE. The courses selected for field tests were a sinusoidal course, a random course, a Belgian pave, and discrete half round obstacles of 6-in. and 8-in. radii, as they represent a wide spectrum of inputs from a single frquency vibratory input to shock inputs rich in all frequencies of interest. The test vehicle was driven at various speeds over all selected terrains. The field tests were conducted using vehicle's laden and unladen configurations, and three track pre-tension settings. A large amount of measurement data was gathered during field testing. The measured data in its entirety was conditioned and reduced for the purpose of ride quality assessment, and validation of the computer ride model.
