| 摘 要： | 应用通径系数法对深松铲关键参数与牵引阻力的关系进行了探讨.分析结果表明,在影响牵引阻力的3因素中,刃角的影响是主要的,其次是翼张角,最小是翼倾角.以上各因素除了对牵引阻力有直接影响外,还存在着程度不同的间接影响,该结论对深松铲的设计提供了一定的理论依据.

| Abstract: | The correlation coefficient between deep-shovel's key parameters and tractive resistance has been investigated with path coefficient. Results of the analysis showed that the most important factor of them is the blade angel concentration,the second is wingspan angel,and wingluff angel is the smallest.Research of indirect path coefficient indicates that all of factors not only have direct influence on tractive resistance,the correlation between the factors but also have indirect influence on it.The conclusion... |
