The application of composite sandwich structure in light-weight structural design is becoming more and more widely,and it has become an integral part in the fields of aerospace and rail transit.Under the condition of many working conditions,the connecting piece of the sandwich structure needs to carry a comparatively large load effect,which makes a more strict requirement for the design of the connecting piece.A combination structure of double-T-type thread connection was designed,several common metal pre-embedded or back-connecting parts were analyzed.And its application method was introduced from the angle of assembly,and the combined structure was simulated and analyzed by the finite element software.A certain reference value was provided for the connection mode of the sandwich structure of the composite material.
