Abstract

The invention relates to the technical field of simulated analysis, in particular to a method for performing simulated analysis on glass glue failure. The method is characterized by comprising the following steps: S1, performing tensile and shear test on a glass glue test sample; S2, obtaining a tensile and shear limiting force curve through the test; S3, obtaining tensile and shear strength limit through the above limiting force curve; S4, according to the tensile and shear strength limit, defining keywords in simulated software to realize tensile and shear failure simulation. According to the method for performing simulated analysis on glass glue failure, provided by the invention, the glass glue failure condition is subjected to simulated analysis, so that the failure of the glass glue connection in the whole vehicle collision simulation can be identical to the failure of the glass glue connection in the actual vehicle collision well, the difference between the local deformation mode of the whole vehicle and the test is small, and the simulation accuracy degree is increased.

Description

technical field [0001] The invention relates to the technical field of simulation analysis, in particular to a simulation analysis method for failure of glass viscose. Background technique [0002] As a common connection method in automobiles, glass glue has its own advantages over traditional spot welding, mainly because glue is also a load-bearing structure and can withstand greater stress. The glass adhesive used for structural connection in automobiles can form permanent high-strength connections between various high-strength metals or non-metals. Epoxy resin adhesives are a typical representative of adhesives. At present, the commonly used glass glue adhesive has a density slightly higher than water, and the yield strength after curing can reach 20-40Mpa. In the actual body design, the glue is mostly used in the position where the shear is the main part, so as to play the role of the adhesive in the shear state. Excellent performance. [0003] At present, the detachme...
