STRUCTURAL HEALTH MONITORING SYSTEM AND METHOD

摘要

A method includes: transmitting, via a signal generator, an electrical driving signal, the electrical driving signal having a mean square error; transmitting, via a wave generating component, a Lamb wave, the Lamb wave having many different modes; estimating, via an estimating component, a propagation parameter associated with the Lamb wave; and estimating, via an estimating component, a thickness of a material.

1. A method comprising:
providing, via a memory component, an initial thickness of a material to be monitored; providing, via a signal generator, an electrical driving signal; generating, via a wave generating component, a Lamb wave from the electrical driving signal; receiving, via a receiving component positioned a predetermined distance from the wave generating component, a received Lamb wave; generating, via the receiving component, an electrical received signal based on the received Lamb wave; estimating, via a first estimating component, a propagation parameter; and estimating, via a thickness estimating component, a new thickness of the material to be monitored based on the initial thickness and the estimated propagation parameter.
