Purpose

The exploration of the polar regions is of immeasurable potential. It brings great challenges to tribology in the extreme environment. Moreover, the static friction force is an essential index of the braking performance. The purpose of this paper is the static friction force between the rubber of marine pipe tensioner and the ice bead.

Design/methodology/approach

The frictional phenomena were studied for rubber-ice bead at different contact positions (front edge, front part and end part) by means of image processing and measuring. Also, the image sequences of the contact were combined with friction force and displacement data.

Findings

As rubber across the ice bead, the forces of rubber and ice bead at different contact positions determined the order of static friction force (front edge > front part > end part). Meanwhile, there were two different contact states in this process. In addition, under the low tangential load growth rate, the higher temperature can increase the static friction force by increasing the viscoelasticity and contact area of rubber.

Originality/value

The research on the static friction of rubber-ice bead leads to more controlled and higher friction levels during marine pipeline laying.

橡胶在冰珠上的摩擦开始

目的

极地地区的勘探潜力不可估量。这给极端环境下的摩擦学带来了巨大挑战。此外，静摩擦力是制动性能的重要指标。本文的目的是船用管道张紧器的橡胶与冰珠之间的静摩擦力。

设计/方法/方法

通过图像处理和测量，研究了橡胶冰珠在不同接触位置（前边缘，前部和端部）的摩擦现象。此外，接触的图像序列与摩擦力和位移数据相结合。

发现

当橡胶跨过冰珠时，橡胶和冰珠在不同接触位置的力决定了静摩擦力的顺序（前缘>前部>端部）。同时，在此过程中有两种不同的接触状态。另外，在较低的切向载荷增长率下，较高的温度可通过增加橡胶的粘弹性和接触面积来增加静摩擦力。

创意/价值

对橡胶冰珠静摩擦的研究导致船舶管道铺设过程中的摩擦水平得到了更好的控制和提高。
