Abstract:
The wear factors of hook assembly of a large heavy-load suspension launcher are studied experimentally and simulated for the pin shaft abnormally unlocking. The working conditions of the hook pin shaft with clearances of 0.05 mm,0.1 mm and 0.15 mm under vibration condition are simulated using dynamic analysis software ADAMS. The influences of shaft and hole matching material,fit clearance and lubrication condition on pin shaft abrasion are studied by contrast experiments and single-factor experiments. The simulation results show that the contact collision stress between the pin and shaft is the smallest for the fit clearance of 0.1 mm,and the pin has the best rotation effect in the hook hole,which is consistent with the experimental results. The experimental results show that the wear of the pin shaft is greater for the hook and pin shaft using same material; the wear of the pin shaft increases with increasing clearance between the hook pin shaft and the hook hole; the 7008 aviation grease between the pin and the hook can reduce the friction between the mating surfaces,the friction heat and the wear and ablation of pin material.
