Stress and/or accumulated damage monitoring system

摘要

The invention provides a stress and/or accumulated damage monitoring system for earth moving equipment, comprising: a plurality of strain gauges (51-60) each gauging strain at one of a plurality of corresponding strain gauge locations; a data acquisition unit (41) to acquire real-time strain data from the strain gauges (51-60); a processor and memory (42) to process the acquired real-time strain data to calculate one or more measures of actual accumulated damage and/or actual instantaneous stress; and at least one output device (37) to provide information comparing the measures with corresponding reference values.
