Abstract
A structural health monitoring system is provided. The system includes a drive system having a first drive member a second drive member 38 operationally connected to the first drive member, and a tension member 39 operationally connecting the first drive member to the second drive member. At least one sensor 50 is configured to monitor a characteristic of at least one of the first drive member and the second drive member. A processor 54, in communication with the at least one sensor, is configured to determine if the structural health of the tension member is compromised based on the monitored characteristic. The processor is further configured to perform a safety response action when the structural health of the tension member is determined to be compromised.
