作者从含橡胶的摩阻材料的摩擦状况出发,对其摩擦机理提出了一个新的观点——气穴排空说,並进行了简单的实验论证。认为弹性材料在与刚性对偶在负荷下接触时,由于材料的弹性变形使接触面间空隙中的气体被排出或部分排出而形成真空状态,因此弹性体上除了受外加负荷之外,还增加了部分大气压力,因而摩擦力也随之增大。摩擦力增大的部分为: △F=f·△P 式中f为材料间的摩擦系数,△P为正压力增大部分,其值可表示为: ΔP=A_(app)·P_(ntm)· 此处A_(app)为表现接触面积;P_(ntm)为大气压强;η为排空率(％)。η受材料弹性模量,负荷及对偶表面状态等的影响。
Based on the rubbing condition of rubber-containing friction material, the author proposed a new viewpoint on the friction mechanism of cavitation-cavitation emptying, and conducted a simple experimental demonstration. It is considered that when the elastic material is brought into contact with a rigid pair under a load, the gas in the gap between the contact surfaces is discharged or partially discharged due to the elastic deformation of the material to form a vacuum state, and thus the elastic body is subjected to an additional load Part of the atmospheric pressure, so the friction also increases. Friction increases the part: △ F = f · △ P Where f is the friction coefficient between the material, △ P is the positive pressure increases the part, the value can be expressed as: ΔP = A · (app) · P_ (ntm ) Where A_ (app) is the contact area; P_ (ntm) is the atmospheric pressure; and η is the empty rate (%). η by the material elastic modulus, load and dual surface state and so on.
