为了提高生产效率,在许多现场,人们希望物体在摆动过程中就进行称重,如使用的吊秤等。所以解决动态称重已是一件十分迫切的任务。目前,国内外都在进行这方面研究,以期提高称重准确度。如果把被称重物的运动近拟地简化为一个垂吊物体的无阻尼摆动,那么日本一专利已有报导。但是为了进一步提高称重准确度,必须 In order to improve the production efficiency, in many fields, people want objects to be weighed during the swing, such as the use of crane scales. Therefore, to solve the problem of dynamic weighing is a very urgent task. At present, both at home and abroad are conducting research in this area, with a view to improving the accuracy of weighing. A Japanese patent has been reported if the movement of the weighed object is reduced to an undamped swing of a hanging object. However, in order to further improve the weighing accuracy, it is necessary
