摘要

材料疲劳现象是指在可变的、周期性重复的应力作用下,材料通过断裂的出现和发展而逐渐发生损伤。设计抗疲劳机械和结构的工程师可以通过查阅文献获得有关设计和材料性能的有用见解。这样,我们可以避免昂贵的研究,但在复杂的加载现象和部件相互作用的情况下,我们必须进行这样的研究。疲劳强度计算不如简单的静态计算准确。根据单个连杆的安装位置和功能,连杆链的磨损集中在三个区域,即:在关节(两个连杆之间的接触点),在拱的外表面和连杆直段的外表面。在操作过程中,链条特别容易磨损,腐蚀和疲劳。这些老化因素根据沉积物的性质以不同的强度起作用,决定了链条的使用寿命,除非发生其他不可预见的损坏,例如:链条“硬”堵塞。在许多情况下,用户以自己的主观标准来评估链的技术状况,这并不总是导致对使用过的链的继续使用做出完全合理的决定。迄今为止,还没有人试图将链条疲劳试验的结果转移到真实物体的行为上。本文介绍了采矿链疲劳试验的相关问题。给出的测试结果适用于新链条和旧链条。在GIG进行的试验试验为解决疲劳试验结果在工业实践中的应用问题提供了可能。

Fatigue Life Testing of the Round Link Mining Chains
Abstract The material fatigue phenomenon consists of progressive material damage through the appearance and development of fractures under the influence of variable, periodically recurring stresses. Engineers designing machinery and structures to be fatigue resistant can gain useful insights about design and material properties by reviewing the literature. In this way, we can avoid costly research, but in the case of complex loading phenomena and the interaction of components, we must carry out such research. Fatigue strength calculations are less accurate than simple static calculations. The wear of link chains is concentrated in three areas, depending on the installation location and function of the individual links, namely: in the joints (the points of contact between two links), on the outer surfaces of the arches and on the outer surfaces of the straight sections of the links. During operation, chains are particularly vulnerable to wear through abrasion, corrosion and fatigue. These ageing factors, which act with varying intensity depending on the properties of the deposit, determine the service life of the chain, unless other unforeseen damage occurs, e.g. "hard" blockage of the chain. In many cases, users are guided by their own subjective criteria for assessing the technical condition of chains, which does not always lead to fully rational decisions regarding the continued use of used chains. To date, there have been no attempts to transfer the results of chain fatigue tests to behaviour of real objects. This paper presents issues related to mining chain fatigue testing. The test results presented are for both new and used chains. The experimental tests conducted at GIG made it possible to solve the problem of applying fatigue test results in industrial practice.
