基于有限元分析的感应钎焊蜂窝板工艺研究
Research on Induction Brazing Honeycomb Panel Process based on Finite Element Analysis
摘要
Abstract
To design a reasonable induction coil structure and investigate the effects of different input currents and heating times on the maximum value of the weld temperature,and to select suitable process parameters,so as to realise the high-efficiency preparation of honeycomb plate induction brazing.In this paper,a finite element model of induction brazing hon-eycomb plate is established,three shapes of coils are designed:spiral coil,double-back coil,M-shaped coil,and the tempera-ture field distributions of induction brazing honeycomb plate with the three kinds of coils are obtained by calculations,and the influences of different process parameters on the maximum value of the temperature are also investigated.On the basis of simulation,brazing test was carried out on honeycomb sandwich structure composed of Ti2AlNb alloy and high-temperature alloy,and it was verified that induction brazing Ti2AlNb/GH4099 honeycomb sandwich structure had good fea-sibility.The helical coil concentrates the magnetic field more at the weld seam,generates more electromagnetic heat,and has a higher brazing efficiency.The spiral coil is more conducive to the generation of a large amount of electromagnetic heat in the induction brazing process,and the brazing efficiency is highest when the current is 1000A and the heating time is 15s,and the mechanical properties of the experimentally obtained Ti2AlNb/GH4099 honeycomb sandwich structure are excellent.关键词
