Test Method for Abrasion and Fatigue Resistance of Axillary Crutch Tips / 中国康复理论与实践

ABSTRACT

@#ObjectiveTo study the method of testing abrasion resistance of axillary crutch tips. MethodsA test method based on pressure analysis in normal use of axillary crutches was suggested, which characterized put 450 N on axis of the tip; the tip or text surface sway 60° for 500000 times in frequency of 40 /min; maximal abrasion thickness after test should be less than 3.3 mm. Experimental facilities were established to carry out fatigue test of wearability. ResultsThe test method suggested can reflect tips abrasion in real context. ConclusionThe text method can be used for tips abrasion and fatigue resistance adjustment.
