摘　　要：用2个LHT-1型粮食回弹模量仪储藏大豆6个月,顶部分别加载150 kPa和300 kPa,理论计算得到粮食回弹模量仪的储粮筒内不同位置的压力(87、115、150、161、211、300 kPa)。利用质构仪对不同储藏压力下的大豆样品进行压缩试验。运用SPSS软件对数据进行分析处理,得出大豆籽粒压缩的最大破坏力(76.77～101.51 N),最大破坏能(68.28～84.12 mJ),表观弹性模量(131.99～200.29 MPa)。结果表明:随着储藏压力的增大,大豆籽粒压缩的最大破坏力,最大破坏能,表观弹性模量逐渐减小。In this paper, soybeans were stored in two LHT - 1 type meter of modulus of resilience of grain. Force of 150 kPa and 300 kPa acted on the tops of two meter of modulus of resilience of grain respectively. The pres- sure （87, 115, 150, 161, 211 and 300 kPa） at different locations of the cylinder of the meter of modulus of resili- ence of grain were calculated by theoretical. The soybean samples storing for 6 months under the different pressure were tested with texture analyzer. The data was analyzed and processed by SPASS software. The experimental had shown that： the maximum compressive force to damage soybean （76.77 - 101.51 N）, the maximum compressive en- ergy to damage soybean （68.28 - 84.12 mJ） and apparent contact elastic modulus （ 131.99 -200.29 MPa） de- creased with the increase of storage pressure of soybean.
