摘　　要：我国东北林区经过多年采伐后,现森林资源主要分布在坡度15°以上地区,这对集材机的爬坡性能要求大幅增加。通过对集材机爬坡过程进行受力分析,得到集材机牵引力、最大爬坡度、爬坡速度和能耗的表达式。对三角履带式集材机ZLY-930E和轮式集材机ZLY-925D的参数进行爬坡度、爬坡速度和能耗的计算和分析,结果表明:在多种集材路面上,三角履带式集材机都能保证空载最大爬坡度达到20°以上,而爬坡速度较低,一般不超过19km/h。轮式集材机不能保证在不同集材路面上空载最大爬坡度都能达到15°以上,但最大爬坡速度都在20 km/h以上。在冬季坡度过大不允许集材机满载通过的路面上,为适当提高集材机爬坡度,三角履带式集材机集材质量可降至2 000 kg,轮式集材机集材质量可降至1 400 kg。The forests in Northeast China are mainly distributed in areas with over 15° slope after many years’ harvesting,causing much higher requirement on skidder gradeability. Through force analysis of the slope climbing process of skidders,formulas calculating tractive force,maximum climbing gradient,climbing speed and energy consumption were deduced in this study. Calculation based on track skidder ZLY-930 E and wheeled skidder ZLY-925 D showed that the no-load track skidder could climb slopes over 20°,and the climbing speed was normally less than 19 km / h. On the contrary,the no-load wheeled skidder could hardly climb slopes above 15°,but the climbing speed was over 20 km / h. On winter roads where the slope was too high for a full-loaded skidder to get through,the wood mass loaded on a track skidder and a wheeled skidder should be reduced to 2 000 kg and 1 400 kg,respectively.
