Enhancing HMMWV Operational Availability Through the Use of an Instrumented Diagnostic Cleat for Condition-Based Maintenance.

摘要

A rubber cleat is instrumented with two triaxial accelerometers to measure the multi-directional response of the cleat due to the forces within the tire footprint of a ground vehicle. The cleat data is used to detect faults in the front and rear suspension in addition to the wheel tire despite variability in the data. This offboard diagnostic technique is proposed to enable condition-based maintenance.
