摘要

高分子材料与金属材料摩擦相互作用过程中的阻力主要依赖于运动输入的动力学特性。在金属-聚合物摩擦副中，载荷静止时的静摩擦阻力取决于引起相对摩擦的力的增长速度。对选定的(聚合物-金属)滑动副进行了摩擦学试验。所选的聚合物有聚氨酯(TPU)、聚砜(PSU)和硅橡胶(SI)。在不同相对运动力梯度(dF/dt = 0.1-20 [N/s])的干摩擦条件下，在统一压力p = 0.5 MPa下，与正火C45钢制销相互作用。根据记录的静摩擦力值确定所选滑动副的静摩擦系数。试验结果表明，运动驱动力的增加速率对静摩擦阻力值有显著影响。这主要是由于聚合物的粘弹性。

INFLUENCE OF THE DYNAMICS OF FORCED MOTION ON THE STATIC FRICTION IN METAL-POLYMER SLIDING PAIRS

The resistance during the frictional interaction of polymeric materials with metallic materials is characterized by a significant dependence on the dynamics of the motion inputs. In a metal-polymer friction pair, the static friction resistance during standstill under load depends on the rate of growth of the force causing the relative motion. Tribological tests of selected (polymer-metal) sliding pairs were carried out. The selected polymers were polyurethane (TPU), polysulfone (PSU), and silicone rubber (SI). They interacted with a pin made of normalized C45 steel under unitary pressure p = 0.5 MPa in dry friction conditions at different gradients of the force driving the relative motion (dF/dt = 0.1-20 [N/s]). The static friction coefficient of the selected sliding pairs was determined on the basis of the recorded static friction force values. The test results show a significant influence of the rate of increase in the motion driving force on the values of static friction resistance. This is mainly due to the viscoelastic properties of polymers.
