Abstract：To improve the reliability of self-locked performances of the function transformation mechanisms in multi-functional clamp-shear-grab integrated attachment，the contact performance of the mechanisms under self-locked states Was studied，and original prototype and test prototype of the mechanisms were designed based on test conditions，and then tests were conducted. Initially，the prototypes of function transformation mechanisms were developed，and a self-locked mechanism was proposed based on slidergroove structure.By thoroughly considering the elastic deformations，adhesions，pileup deformations，and sliding shear contact states under self-locked states，an innovative contact model was proposed. Based on these，the self-locked states and contact characteristic distributions of slider-groove in contact areas were studied through finite element analyses.Finally，experiments were designed to verify the feasibility of the model and design.Experimental results show that the prototype may achieve self-locked function and exhibits good mechanics performance，and the proposed contact model outperforms traditional model by （204号 59.3% in terms of maximum shear stress relative error.
