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.

摘要： Methods and apparatus for diagnosing the condition of a vehicle. Some embodiments include providing an input to a vehicle suspension similar to an impact, and then measuring the response of the vehicle as it drives over an instrumented member. The motion of the instrumented member is recorded and corrected, and in some embodiments a fault index is calculated. The fault index can be displayed to a user to indicate a maintenance condition of the vehicles, such as a worn or broken component.
