本文在对金属-土壤摩擦机理讨论的基础上,提出了用非牛顿流体方程描述摩擦阻力与滑动速度的关系。并结合应变率过程理论,推导了摩擦阻力与滑动速度、正压力之间的关系式。作者进行了大量的验证试验,表明上述关系式是适用的。试验还得到了摩擦阻力与含水量的关系,并考察了金属表面泥膜对摩擦阻力的影响。
Based on the discussion of metal-soil friction mechanism, this paper presents the relationship between frictional resistance and sliding velocity by non-Newtonian fluid equations. Combined with the theory of strain rate process, the relationship between frictional resistance, sliding velocity and positive pressure is deduced. The author conducted a large number of validation tests, indicating that the above formula is applicable. The relationship between friction resistance and water content was also obtained. The influence of mud film on friction resistance was also investigated.
