ASPECTS REGARDING SHEARING CUTTING BLADES FEATURES OF ENERGETIC PLANTS STRAINS FOR LABORATORY TESTING

Abstract

Testing shear cutting parameters of energetic plant strains it is realized in laboratories with modern equipments with two pillars and an adequate cell force.Direct shear testing of stalks it is realized with metallic blades with a V opening, the center angle being 60, 75, 90 or 120 degrees (or others). For shear cutting testing of miscanthusgiganteus strains with a testing equipment type Hounsfield H1 KS, cutting blades of the same dimensions with shearing blades were made (same length, thickness, angles openings) but with the two sharp edged at different angles (10, 20, 30, 40, 50 degrees). Experimental testing objective was to identify the most adequate sharpening angle and blades opening for a maximum efficiency in plant cutting (minimum energy consumption).. In this paper testing sheets characteristics and the results obtained by cutting plants are presented.
