| 摘 要： | 为构建挂面弯曲折断率仪器测定方法,用三点弯曲法测定了4种挂面的弹性模量;用压杆法测定了挂面端部轴向位移量与端部转角之间的关系,并与挂面压杆力学模型的端部转角计算值进行了比较.结果表明,端部转角计算值与实测值之间的误差均小于5°,挂面端部轴向位移量与端部转角呈线性正相关关系,合格挂面弯曲折断率的端部轴向位移量应大于12mm.用端部轴向位移量的测定方法评价挂面弯曲折断率是可行的.

| Abstract: | In order to construct an instrumental method for determining bending fracture rate of noodles,the elastic moduluss of four kinds of dry noodles were measured by using a 3-point bending test.The relation between the end axial displacement and the end bending angle of dry noodles was determined,and the values measured by this method and the values calculated by compressive rod mechanical model were compared.The results show that the errors between the values calculated and measured for the end bending of dry ... |
