摘　　要：现代仿真技术的应用极大地提高了工业产品的设计能力,其中以有限元算法应用最为广泛。文中以某型雷达的传动结构为研究目标,运用有限元软件对其进行刚强度分析。通过建立刚性区域,耦合主节点自由度来模拟运动关系的约束关系,并考虑结构对称性以简化计算模型,得到整个传动结构部分的应力位移分布,为结构改进提供理论依据。Applications of simulation technology have greatly improved the design ability of industrial products,in these technologies,finite element method has got the most wide use.This paper has the transmission structure of radar to be the target,and uses the finite element analysis software to compute the stiffness and strength.By the use of rigid region,coupling the degree of freedom of master node to simulate the constraint relations of movement,and simplifying the model by considering the structural symmetry,the paper obtained the distribution of stress and displacement,and provided theoretical basis for the structural improvement.
