| 摘 要： | 为使真实路面激励可以用于喷杆喷雾机的系统辨识和系统特征评价,建立了在路面单侧激励条件下,从路面激励相继作用于喷雾机前、后轮时的喷杆运动响应中,提取路面激励仅作用于喷雾机前轮时的喷杆理想运动响应的方法.试验结果表明,所提方法可获得与实测响应值间可决系数为0.955 1的模型预测值.获得的喷杆理想运动响应用于喷杆运动响应特性分析的同时,也为路面激励仅作用于喷雾机后轮时的喷杆理想运动响应的提取提供了依据.

| Abstract: | To make sure the excitation of a step track can be used for boom sprayer system identification and characteristics estimation,a method was established to extract the front-tires-excited spray boom response form the spray boom response of front and rear tires were excited by step truck.The determination coefficient between measured and predicted model value of spray boom response was 0.9551.The front-tires-excited spray boom response can be used for characteristics analysis of spray boom motion. |
