| 摘 要： | 对油菜裸苗茎秆进行物理机械特性试验,包括不同生长期油菜裸苗茎秆截面直径的测定,不同生长期油菜裸苗茎秆的压缩、剪切、拉伸试验。试验研究了油菜裸苗茎秆直径随生长时间的变化规律以及油菜裸苗茎秆压缩、剪切、拉伸极限随生长时间的变化规律,建立了油菜裸苗茎秆截面直径与生长时间的数学模型。研究表明:湘杂1613的油菜裸苗茎秆直径的增长与生长时间呈线性关系;油菜裸苗茎秆的耐压、耐切、耐拉的能力随时间的增加而增加。该结论为设计移栽机械提供了初步的实验基础,同时为进一步研究油菜移栽机械取苗、护苗、栽插参数等关键部件结构和运动学、动力学参数提供了理论依据。

| Abstract: | The test studied the variation of diameter and compression,shearing,tensile limitation of rape naked seedlings stalks with the growth time,and set up the mathematical model about the relationship between diameter of rape naked seedlings stalks section and growth time.The result show that the Xiangza 1613 rape has a linear relation between diameter of naked seedlings stalks and growth time;the resistance to compression,shearing,tensile capacity improved with the increase of time.The results provide data and ... |
