摘要  针对喷灌和软管灌溉两用轻小机组洒水车具有高度可升降、喷幅可调、喷灌和软管灌溉两用等特点,为了提高洒水车爬坡和抗翻倾能力,对该机组洒水车纵、横向稳定性进行了分析.采用理论分析的方法分析了机组在纵横向坡度上作业时影响其稳定性的因素,并给出了其稳定性与各影响因素之间的关系.结果表明,地面粘附系数越高,对洒水车的稳定性越有利;适当增大轮距、增大两轮中轴线至供水管触地点的距离、降低洒水车质心高度,可提高洒水车的稳定性;增大牵引力和减小洒水车自重可提高洒水车的爬坡能力.

Abstract: In ordor to improve the abilities of slope-climbing and overturn-resisting of light weight and small size watering cart for dual purpose of both sprinkling irrigation and hose irrigation, the vertical and horizontal stabilities of the cart were analysed. The factors that affect stabilities of the device in vertically and horizontal slope were theoretically depicted, the relationship between stability and various factors were discussed, and gradient angle for no-gliding and no- overturning was calculated. Results show that higher viscidity coefficient of ground possess more favorable advantage for the stabilities of the cart. The stabilities of watering cart can be improved effectively by ways such as increasing the spacing of wheels and that between the mid axes of wheels and the touchdown point of flow pipe, reducing the hight of barycenter. The climbing ability can be improved by ways such as increasing the traction and reducing the weight of watering cart.
