引言推土机之模化,是对于原型设备性能特征在特定(简化)条件下的一种相似再现。模化为科技开拓者考察工程机械工作规律,系统参量间信息传递的规律,开发机械性能,提供一种简便、易行、经济的仿真实验手段。在研究过程中,我们充分利用了此种手段,并通过多次重复的模化实验,深刻具体地揭示了推土机在牵引作业工况下,其履带接地段上的比压分布同机器重心,履带相对地面滑转率各参量之间的相关关系,从而为消化新结构、开发新产品,提供了从感性到理性上的启示。
Introduction Bulldozer modeling is a similar reproduction of the performance characteristics of prototype equipment under certain (simplified) conditions. Modeling for the pioneer of technology to examine the working rules of construction machinery, the system of information transmission between the law, the development of mechanical properties, to provide a simple, easy and economical simulation experiment. In the process of research, we make full use of this kind of means, and repeated modeling experiments revealed that the bulldozer under the traction operating conditions, the track section of the pressure distribution of the machine with the center of gravity, the track Relative ground slip rate of the correlation between the various parameters, so as to digest the new structure, the development of new products, provided from the perceptual to rational enlightenment.
