In this paper,the mult-point edge support structure model of the mult-point edge support structure with adhesive layer connection is established,and the influence of adhesive layer thickness on the surface shape of mult-point edge support light window is analyzed by simulation.The finite element analysis model of "pressure block glue layer light window" is established.Under the condition of structure course overload,course random vibration and high and low temperature impact,the simulation results of different adhesive thickness are processed,and the influence of adhesive layer thickness on the surface deformation of light window is analyzed.The results show that: in the range of 0.1~0.5 mm,PV value and RMS value of light window surface show a trend of first decreasing and then increasing with the increase of adhesive layer thickness in the simulation test of overload impact and random vibration;in the simulation of temperature impact,it shows a trend of gradual decrease.
