Abstract: Helicopter simulation target is a kind of live fire training target commonly used in military training field. The structural strength of the helicopter target is very important for its safe and stable operation. In this paper, taking the trussed helicopter target as the research object, the force analysis of its core supporting component-truss under different working conditions is carried out, and then the static analysis is conducted by using the finite element method. It provides the theoretical basis for the structural design and safety evaluation of the trussed helicopter target.
