摘　　要：以"华杂4号"和"华杂7号"油菜籽为对象,测试分析了一定工况下两种油菜品种的压缩的机械物理特性及其相关参数的变化规律。结果表明:"华杂4号"和"华杂7号"油菜籽的最大载荷和屈服载荷都与其直径显著相关,随着油菜籽直径的增大而增大,且呈2次多项式关系增大。相比较而言"华杂7号"油菜籽的最大载荷值和屈服载荷值高于"华杂4号"油菜籽,研究结果为开展油菜籽排种器的结构设计及其降低油菜排种器种子破碎率提供了重要的理论依据和参考价值。In this paper,the compressing characteristics and parameters of Huaza 4 and Huaza 7 rapeseed have been studied experimentally.The study shows that both the maxmum load and yield load of the two types of rapeseed have significant correlation with the diameter.And they are increasing with a quadratic polynomial in diameter.Comparatively speaking,the the maxmum load and yield load of Huaza 7 type rapeseed are bigger than those of Huaza 4 type rapeseed.The results provide important theoretical basis and reference value for designing metering device of rapeseed and analyzing to reduce its damaged rate.
