拖拉机重心高度测定方法和装置的研究

Study on method and equipment for measuring weight-center position of tractor.

在原有拖拉机作摆的运动时周期与重心高度间关系的理论模型基础上,提出实用的实测模型,完成了测定装置的研制,且以该实用装置测定了拖拉机重心高度,并与常用的称重法进行比较和精度分析.

The determination of the weight-center position of a tractor is necessary for the solution of many problems,for example,of the transverse and longitude balance,of the satety of a tractor,of the response when a tractor is speeding up,and so on.On the basis of the theoretical model, the study has given out the practical model and the practical eguipmment for measuring weight-center position of a tractor. A practical example is measured with the eguipment and the re-suits are analised.
