摘要
从车辆行驶性观点出发 ,测出了新疆塔克拉玛干沙漠沙载荷—沉陷曲线 ,建立了沙的Bekker承压特性公式。提出一种描述沙承压特性的新模型 ,计算结果与实测值基本一致。
Tests have been conducted in a soil bin to study the interaction between vehicle and terrain so as to investigate the relationship of pressure sinkage of Takelamagan desert sand in Xinjiang. Bekker's formulae is first used to describe the relationship of pressure sinkage of the desert sand. A new model for predicting the relationship of pressure sinkage of the desert sand is then presented. Comparison between results of computation with the new model and test results is made. It is found from the comparison that there exist a fairly close agreement between them. These results lay the foundation for further studies in the interaction between vehicle walking machine and the desert sand, and in the development of desert vehicle.
