Simulation analysis of double shear test for titanium alloy fasteners
摘要
Abstract
Double shear tests were conducted on low clearance TI-6AL-4V ELI hexagonal titanium alloy bolts.The finite element simulation method was used to analyze the influence mechanism of shear rate,blade radius,shear gap on bolt performance,as well as the degree of influence of each factor on bolt mechanical properties.The results show that when the blade radius was 0.1 mm,the simulation results had the largest error compared to the ideal simulation results.The influence of shear rate on the experimental results was relatively small.When the shear rate was 366.7 N/s,the energy absorbed by the bolt shear section was higher.The shear gap had the greatest impact on the results of bolt double shear test.As the shear gap increased,the error between the simulated results and the ideal simulation results gradually increased.This indicated that when conducting bolt double shear test,the shear gap should be strictly controlled to avoid its impact on the results of bolt double shear test.When the blade radius was 0.2 mm,the shear rate was 666.7 N/s and the shear gap was 0.002 5 mm,the error between the simulation results and the ideal simulation results was the smallest.关键词
