摘　　要：螺旋推进式车辆的接地压力值较低,适宜在湿软地面行驶,考虑到车辆的两栖性、机动性,可知螺旋推进式车辆是一种可行的行走方案。该次车辆地面力学实验包含对土的紧实度试验、土的直剪试验、土的三轴剪切试验等进行实验,得出大量实验数据,进一步绘制关系曲线。了解土的疏密与土体内部结构的密实情况,为进一步研究车辆与地面之间相互作用提供一个基本指标,为提高车辆机动越野能力提供数据支撑。The grounding pressure value of the spiral propulsion vehicle is low,and it is suitable for driving on the wet and soft ground.Considering the amphibiability and mobility of the vehicle,we can know that the spiral propulsion vehicle is a feasible walking scheme.The vehicle ground mechanics experiment includes the compactness test of soil,direct shear test of soil,and triaxial shear test of soil,and obtains a large number of experimental data,and further draw the relationship curve.Understanding the density of soil and the density of soil internal structure will provide a basic index for further research on the interaction between the vehicle and the ground,and provide data support for improving the vehicle motorized off-road capability.
