摘要： 为了提高车载式液态融冰雪剂洒布机的洒布质量,采用理论分析与试验研究相结合的方法,分析了车速波动和液态融冰雪剂输送泵的泵速波动对洒布质量的影响。提出了基于随速洒布的泵速调节控制系统。实车试验结果表明:当车速小于某临界车速时,泵速保持阈值不变,实际洒布量偏离目标洒布量,但保证不出现条纹状缺陷;当车速大于该车速时,输送泵的转速在控制系统作用下随车速波动自动调节,实际洒布量接近目标洒布量。

Abstract: To improve the spraying quality of vehicle-mounted sprayer for liquid deicing and snow-melting agent, the influences of the fluctuations of the vehicle speed and the agent pump speed on the spraying quality are discussed. A pump speed control system is proposed under the condition of varying vehicle speed with the help of theoretical analysis and field test. Experiment results show that, when the vehicle speed is slower than a critical value, the pump speed maintains the threshold and the actual spraying volume deviates from the target value, but there is no striped spraying defect. If the vehicle speed exceeds the critical value, the pump speed would be automatically adjusted by the control system according to the vehicle speed and the actual spraying volume is close to the target value.

Key words: road engineering, liquid deicing and snow-melting agent, sprayer, spraying quality, uniformity coefficient
