摘要
通过对法兰进行设计,开展相应结构的有限元分析,分析了法兰锥颈角及花形设计对法兰强度和刚度的影响。结果表明,花形设计中锥颈角的增加会导致环向和轴向应力减小,对径向应力影响不大,整体法兰的刚度随锥颈角和法兰厚度的增大而增大。同时采用拓扑结构对法兰进行花形设计,优化了花形法兰设计。
Through optimal design and finite element analysis, the effect on flange intensity and rigidity of flange taper angle and lace configuration were evaluated. The results indicate that as flange taper angle increases, circumferential stress and axial stress decreased, while radial stress changed less, the rigidity of integral flange grows up as flange taper angle and flange thickness increased. Through topological structure design, the optimal lace flange configuration was obtained.
