谷子秸秆生物力学性质试验研究
Experimental study on the biomechanical properties of millet stem
摘要
Abstract
Millet stem can be used as forage to fed livestock directly such as horse and mule.It also can be used as bur-den of the mixed feed.The biomechanical properties of millet stem should be studied to provide the selection of some design parameters on processing equipment like crushing process,dissection process,pulverization process and its process parameters optimization.In this paper,biomechanical properties of natural drying millet stem have been stud-ied,mainly testing its bending strength,shear strength,tensile strength and elastic modulus.The results showed that the bending strength of millet stem was superior,with its tensile strength closing to wooden materials.While its shear-ing strength varied along different internodes,greater in the root and lower in the upper.What the bending strength reflects on was the limit value of bending failure of integral tubular section.Elastic modulus hardly change,manifesting its integration was uniform.All of these provide the beneficial reference for many sides such as the millet stem reaping, processing and utilization as well as the designing of agricultural equipment and facilities.关键词
