本文根据弹塑性理论与摩擦机理,对塑性变形接触区中的摩擦与摩擦力进行了探讨,并提出如下论点:①根据摩擦副之间介质的存在,确定摩擦性质和区分摩擦类型;②库仑定律T=μP只适用于弹性或弹塑性变化范围;③在塑性变形区τ、μ、P不是常数;摩擦力T为摩擦副接触表面之间的摩擦力F与金属开始塑性变形时内部最大剪切力τmax之和,即T=F+τmax。还对滑-粘等问题进行了探讨,同时对现有的几种具有代表性的论点及计算方法进行比较和提出了看法。
Based on the theory of elasto-plasticity and friction mechanism, this paper discusses the friction and friction in the contact area of plastic deformation and puts forward the following arguments: ① According to the existence of the medium between the friction pair, determine the friction properties and distinguish the type of friction; ② Coulomb’s law T = μP is only applicable to elastic or elastic-plastic range; ③ in the plastic deformation zone τ, μ, P is not constant; friction T is the friction between the contact surface friction F and the metal begins to plastic deformation of the internal maximum shear The sum of the forces τmax, ie T = F + τmax. At the same time, some existing representative and calculation methods are compared and put forward.
