1. A method of constructing a load history database for a structure, comprising:
- detecting a measurable parameter on the structure utilizing a sensor positioned on the structure;
determining a value of external loads acting upon the structure based on the detected parameter;
evaluating the value of the external loads against a pre-established factor;
selectively storing the value of the external loads in the load history database based upon the evaluation against the pre-established factor, wherein selectively storing the value of the external loads includes storing the value of the external loads acting on the structure during a determined period of time; and
determining a damage rate of the structure based upon the value of the external loads over the determined period of time.

Abstract
Methods and systems for constructing a load history database for a structure is disclosed. In one embodiment, a method is disclosed that may include detecting a measurable parameter on the structure utilizing a sensor positioned on the structure and determining a value of external loads acting upon the structure based on the detected parameter. Further, the method may include evaluating the value of the external loads against a pre-established factor. Based on the evaluation, the value of the external loads are selectively stored in the load history database.

9. A method of constructing a loading history database for a mobile machine, comprising:
-
detecting a measurable parameter of the mobile machine with a plurality of sensors permanently positioned onboard the mobile machine during operation of the mobile machine; maintaining stored data reflecting a previously stored lifetime maximum external load and a lifetime minimum external load acting upon the mobile machine that was caused by operation of the mobile machine; analyzing the measurable parameter to detect a new lifetime maximum external load or a lifetime minimum external load acting upon the mobile machine that is caused by operation of the mobile machine; updating a memory component to replace the previously stored lifetime maximum or minimum load with the new lifetime maximum or minimum load when the new lifetime maximum or minimum external load acts upon the mobile machine; maintaining data indicative of a previously stored loading scenario at a desired percentile of damage rate severity for the mobile machine; monitoring the measurable parameter to detect a new loading scenario that agrees more closely with the desired percentile of damage rate severity for the mobile machine than the previously stored loading scenario; and updating the memory to replace the previously stored loading scenario with the new loading scenario when the new loading scenario agrees more closely with the desired percentile of damage rate severity for the mobile machine than the previously stored loading scenario. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method for managing a load history database for a mobile machine, comprising:
-
collecting measured data received from sensors positioned onboard the mobile machine during operation of the mobile machine; determining a current damage rate caused by operation of the mobile machine based on the collected measured data; determining a first relationship between the current damage rate and a predetermined target damage rate; comparing the first relationship with a second relationship reflecting a relationship between a previously determined damage rate caused by operation of the mobile machine and the target damage rate, the second relationship being stored in the database; and replacing in the database the second relationship with the first relationship based on the comparison. - View Dependent Claims (16)
