STRESS AND/OR ACCUMULATED DAMAGE MONITORING SYSTEM

摘要

A system provides stress and/or accumulated damage monitoring on earth moving equipment, such as excavators, trucks, electric rope shovels and drills, hydraulic shovels, wheel loaders and graders. The system includes: strain gauges (51-60), each gauging strain at one of multiple 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.

1. A stress and/or accumulated damage monitoring system for earth moving equipment, comprising:
a plurality of strain gauges each gauging strain at one of a plurality of corresponding strain gauge locations on earth moving equipment, the earth moving equipment selected from the group consisting of an excavator, a truck, a shovel, a drill, a wheel loader, and a grader; a data acquisition unit to acquire real-time strain data from the strain gauges; a processor and memory 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 to provide information comparing the measures with corresponding reference values.
