Vehicle structural health monitoring (SHM) based on small probability

Executing structural health monitoring(SHM)on vehicle is central to meet the goals of increasing its ability to complete given mission and reducing the repair and maintenance cost while evaluating current health status of the vehicle automatically.At present,being a new field in aviation,SHM attracts more and more focus on it.It addresses the technology based on small probability used in the vehicle structural health monitoring(VSHM)to identify fault in the structure component.Then,taking a wing box segment as research object,the vehicle structural health monitoring system is established with the help of virtual instrument(VI)technology.
