Description

technical field [0001] The invention relates to a virtual strength test system for an unmanned aerial vehicle, which belongs to the technical field of virtual simulation. Background technique [0002] In the process of aircraft development, the strength test is used to determine whether the product design strength meets the design requirements, which is an indispensable link in the product development process. The main method of strength test is physical test. Although physical test is accurate and reliable, it also has shortcomings such as high test site requirements, long preparation period, time-consuming and labor-intensive product modification after test, and serial working mode. Moreover, due to the fast iteration speed of UAV products, this puts high demands on the preparation period, test cost and labor cost of physical tests. [0003] With the improvement of computer technology and simulation modeling technology, virtual test technology has become an important test...
