摘  要:按照美国农业与生物工程师协会ASAE S368.4DEC2000(R2006)标准,使用Brookfield质构仪测定了黑龙江大豆籽粒(2011年产)的表观弹性模量、最大破坏力、最大破坏力能、破坏时的变形量。试验选定压缩速度为:0.02、0.1、0.5、1.0 mm/s,选定压缩方位为长轴(X轴)、中轴(Y轴)、短轴(Z轴)。由质构仪软件,得到了加载载荷与对应变形量的关系曲线,运用spass软件对数据进行分析处理,得到大豆的表观弹性模量、最大破坏力、最大破坏能、破坏时的变形量。试验结果表明:随着压缩速度的增加,大豆籽粒沿长轴(X轴)、中轴(Y轴)、短轴(Z轴)压缩的最大破坏力增大,最大破坏能增加,压缩变形量增大,表观弹性模量减小。According to the American Society of Agricultural and Biological Engineers ASAE S368.4 DEC2000 (R2006) standard, the apparent elastic modulus, the biggest destructive force, the biggest destructive energy and the deformation of the Heilongjiang's soybean (produced in 2011 ) are measured with Brookfield texture analyzer. The com- pressive velocities (0.02 mm/s, 0. 10 mm/s, 0.50 mm/s and 1.00 mm/s) are selected to compress the soybeans in direction of long axis (X) ,middle axis (Y) and short axis (Z). The relation curves of load and the deformationare made with texture analyzer software. The apparent elastic modulus, the biggest destructive force, the biggest destruc- tive energy and the deformation are obtained by the Spass software. The experimental results show that the biggest de- structive force, the biggest destructive energy and the deformation increase with the increase of the compressive veloc- ity in compressing direction of long axis ( X), middle axis (Y) and short axis ( Z), but the apparent elastic modulus decreases with the increase of the compressive velocity.
