Strength Analysis on the Truss Structure of a Helicopter Simulation Target

直升机模拟靶标是一种军事训练领域常用的实弹训练靶标,其结构强度对其安全、稳定运行十分重要。该文以某桁架式直升机模拟靶标为研究对象,在不同工况状态下对其核心支撑部件-桁架进行了受力分析,然后利用有限元分析的方法进行静力学分析,得到其最大应力及最大变形数据,从而为桁架式直升机模拟靶标的结构设计及安全评估提供理论依据。

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.
