本文对奶牛动态称重进行了研究。描述了一个模拟奶牛行走的简单物理数学模型。将奶牛运动的四足系统简化为两足系统。该模型的输出，即牛的脚对地面产生的力，取决于行走速度和体重。所开发的模型用于当奶牛通过步行称重秤时的体重测定。与静态测量的体重相比，在没有动物拥挤通过平台的情况下，可以实现2%的准确度。(C)2004 Elsevier B.V.保留所有权利。
The paper deals with the dynamic weighing of dairy cows. A simple physical-mathematical model that simulates cow walk is described. The four-legged system of cow movement is simplified as a two legged system. The output of the model, which is the force to the ground produced by a cow's feet, depends on walking speed and body weight. The developed model was used for body weight determination as cows crossed a walk-through weighing scale. An accuracy of 2% compared to statically measured body weight could be achieved in the absence of crowding of animals traversing the platform. (C) 2004 Elsevier B.V. All rights reserved.
