Instrumentation Development: The Multiple Subsystem Timing Meter (MSTM).

摘要

In testing Army vehicles such as the Bradley Fighting Vehicle (BFV), it is necessary to maintain accurate operational time records of critical component and/or subsystems. This data is required to determine the mean-time between failures (MTBF) or service life of the components or subsystems. A resettable instrumentation system was designed which was capable of recording turrent subsystem operating times and displaying them in tenths of hours without adversely affecting the subsystems on which data was to be collected. Originally, operational times were to be collected on three turrent subsystems of the BFV: turret power, turret drive, and the Stab system. The Multiple Subsystem Timing Meter (MSTM) was developed to record operational times for the turret drive, turret power, infrared sight unit and the Stabe system on the Bradley Fighting vehicle. One resolvable problem was encountered with the high dust concentration during field testing. (No Failures Occurred during field testing). (JHD)
