针对两栖履带式车辆接地比压的分布规律对车辆牵引性能的影响,大量的研究工作均是基于土壤塑性理论下线性的摩尔-库仑屈服准则。而实际大多数土壤的破坏包络线是曲线。本文采用基于多孔介质下“有效应力原理”的土壤非线性屈服准则来研究压力分布对附着力的影响问题。
In view of the influence of the distribution of amphibious crawler track on the traction performance of vehicles, a great deal of research work is based on the linear Moore-Coulomb yield criterion under soil plasticity theory. In fact, most of the soil damage curve is a curve. In this paper, the nonlinear soil yield criterion based on “effective stress principle” in porous media is used to study the influence of pressure distribution on the adhesion.
