Abstract

The stability of the boom system of sprayers is easily affected by the liquid sloshing force and the uniformity of droplet deposition deteriorates. Therefore, the liquid sloshing forces in the rectangular tank were measured through experiments. Three main factors affecting the sloshing forces were examined. Experimental results reveal that the sloshing forces measured fit well with the theoretical curve and the maximum sloshing force is independent of the excitation amplitude for a violent sloshing. Based on these characteristics, a practical method was proposed which can approximately calculate the maximum sloshing force based on the linear model, and can be used for the sprayer chassis design and active and passive control of boom attitude.

喷雾机喷杆系统的稳定性易受液体晃动力的影响，导致液滴沉积均匀性变差。因此，实验测量了矩形药箱中的液体晃动力。探讨了影响晃动力的三个主要因素。实验结果表明，测得的晃动力与理论曲线吻合很好，大幅晃动时最大晃动力与激励幅值无关。基于晃动力的这些特点，提出了一种近似计算最大晃动力的实用方法，可用于喷雾器底盘设计及喷杆姿态的主被动控制。
