    摘要:

    使用500N微機(jī)控制材料試驗(yàn)機(jī)，利用壓痕加載曲線，進(jìn)行了用針尖壓入法測(cè)定谷物籽粒硬度的試驗(yàn)研究，測(cè)得豌豆、蠶豆、大米、綠豆、小麥、扁豆以及玉米在不同組成部位、不同含水率時(shí)的硬度值在2～75MPa范圍內(nèi)。研究表明，試驗(yàn)加載速度在0.25～2.00mm/s范圍內(nèi)、針尖壓入深度在0.25～1.50mm范圍內(nèi)時(shí)對(duì)試驗(yàn)結(jié)果無(wú)明顯影響，而針尖錐度與籽粒硬度存在定量關(guān)系。

    Abstract:

    By using the 500N microcomputer control material testing machine, based on the load-depth curve, the hardness of the grains was experimentally studied adopting needlepoint pressing-in method. The peas, horsebeans, rice, mung beans, wheat, lentils as well as corn at different moisture and component parts were tested and analyzed, with the measured hardness range of 2～75MPa. The research showed that at the loading speed in 0.25～2.00mm/s and depth of indentation in 0.25～1.50mm, no obvious effect appears in the test results. The taper of needlepoint and the value of grain hardness have a quantitative relation in the measurement.
