Popis:	At present, health monitoring technology of large structures has been paid more and more attention, among which structure measurement system based on PVDF piezoelectric film sensor has been widely used in various fields. To solve the problem that large structural parts of aerospace are easy to be damaged, a load measurement system based on PVDF piezoelectric film sensor is built in this paper given the complex design structure of aerospace. A large cylinder of aerospace is taken as the test part, the stress state of structural parts is measured online, and the corresponding load value is obtained. With the load value, damage to the health state of the structural parts when they are overloaded by external force can be avoided.
