【摘要】 运用力学分析和试验的方法,研究了曲面分隔型碎石布料器导料槽与水平面之间的夹角、导料槽的宽度、布料端的弧度等结构参数,分析了车速对布料器撒布均匀性的影响。设计了宽幅碎石布料器样机,并进行了现场试验。测试结果表明:采用曲面分隔型碎石布料器的试验样机碎石撒布精度为±1.2%,高于采用平面分隔型碎石布料器样机的碎石撒布精度。更多还原

【Abstract】 Based on mechanic analysis and experiment,the angle between the guide grooves and level,the width of the groove,the end radian of the distributor and the chippings bestrewing quality influenced by the velocity are studied.A broaden chippings distributor is designed and tested.The result shows that the bestrewing precision of the experiment machine is ±1.2%,which is better than that of the divided plane chippings distributor.5 figs,9 refs.更多还原
